The first scientific analysis of images taken by NASA's Perseverance rover has now confirmed that Mars' Jezero crater -- which today is a dry, wind-eroded depression -- was once a quiet lake, fed steadily by a small river some 3.7 billion years ago.
The images also reveal evidence that the crater endured flash floods. This flooding was energetic enough to sweep up large boulders from tens of miles upstream and deposit them into the lakebed, where the massive rocks lie today.
[...] "We now have the opportunity to look for fossils," says team member Tanja Bosak, associate professor of geobiology at MIT. "It will take some time to get to the rocks that we really hope to sample for signs of life. So, it's a marathon, with a lot of potential."

At least one of those things is based wildly on hypotheticals and faith, just as much as the "controversial" side.

I think that one thing is based on a lot of hypotheticals and faith on both sides of the argument.
For the record I believe in creation. That said, I understand the overwhelming record of evidence for evolution and the big bang. Things we can see and measure in the universe and on this planet. I find astrophysics to be more persuasive, to me, than geological evidence.
No matter how it got here, I accept the world as it is, with all of the facts that we can observe and measure. Creation is similar to me stating that the universe as we see it today, including all our memories, was all created by my cat last Thursday. Untestable.
We do observe evolution at work. In organisms that reproduce much more quickly the effect of adaptation and selection is more easily observed. Like bacteria.
If your ball of goo is Play-Doh, then nothing may happen. If your goo is very long chain complex molecules -- what we would call organic molecules -- and there is some energy in the system to keep mixing them up for 500 million years, then something might happen. By pure chance. How likely is it that I could flip a coin ten times and get ten heads? Unlikely. But if I do it enough times, it becomes almost certain to happen.

Reproduction of an experiment does not necessarily mean going back and redoing it completely. It's obviously ridiculous to propose that we dump a ball of goo on a planet, wait 500 million years and see if humans evolve from it. But we _can_ run smaller scale experiments and extrapolate. That's what P values are for!

My theory is a lot more magical than you are prepared to accept. Then again, I don't know you, so who am I to judge. The biblical Creation of Earth in seven days. That still begs the question, where did God come from. Yet, I am willing to take it on faith that my ancient ancestors weren't anymore akin to Gorillas than you or I.

You're assuming that speciation is accompanied by everlasting symmetry.
There's no reason for that, and, more importantly, there's no known mechanism for that. On top of that, there are good reasons why it should be false - read some Gould, the pressures that affect one species significantly need not effect its nearest cousins at all - if that was their evolutionary deviation. The equilibria have no reason to line up, or last as long, at all, and the punctuations thereof have no reason to be equal in effect.
It's an assumption that should not be made, and given that if you test it, it fails horribly, it should be rejected.

I find the whole "7 Days" thing very interesting. Most people (perhaps yourself too) believe that a lot of the Bible is written in parable, rather than to be taken as the literal truth. Read that way, the 7 'days' (phases) of creation actually follows the Big Bang and theory of Evolution. The two are actually compatible. As for what caused the Big Bang, God is as good an answer as any other we have. An all-knowing God could create the rules of the universe, knowing the mechanisms that would lead to the creation of single-celled life and the adaptations and mutations that would eventually give rise to humans. In other words, he wrote the program that is currently running, but works on a much longer time-scale than humans can comprehend.
Given you believe in a literal 7 day (144 hours of work and 24 hours of rest) creation (presumably 6,000 years ago?), there are some questions that remain:

Those are all good questions. I've pondered that for much of my life. Of course, I don't know. It does seem like the creation was built as if it had a long history. If I were to create a sophisticated detailed universe as some sort of hypothetical computer simulation using technology we don't have, that simulation would probably be filled with things that had just happened yesterday, or last week, or millions of years ago, etc. If you cut down a tree in the garden of Eden, would it have rings? I think so.
I have no problem with the history of the universe that smart people deduce based on observations and measurements; ether with their own senses or instruments that augment their senses.

#1 The Flood, it caused all kinds of destruction and was responsible for the weird mass graves of the dinosaurs. In the event that you believe that the fountains of the deep were broken up and the heavens opened up/poured down rain. The devastation a world wide flood could easily be the cause of the "weirdness". Ditto, #2.
#3 Why are you putting so much faith in being able to accurately determine the weathering patterns of a few thousand years or so?
#4 The belief is that the garden of Eden and Creation was perfect at the time of Creation, up until the time that humans first sinned. After which, the ground was cursed, snakes could no longer fly (yes, there is a gliding snake), etc. There are at leas two schools of thought on dinosaurs. First thought, God created them, but he knew they wouldn't be able to survive post-flood, so he let them die in the flood. (My wife's preferred version, because she likes dinosaurs.) Second thought, they were amalgamations created by evil men and/or Satan. Imagine an entire people of Geniuses who could live nearly 1000 years. The real decline in human health/vigor came after the flood, Noah lived a total of 600 years or so and subsequent generations died off much faster. Imagine what some of our geniuses have accomplished, then multiply their life span by 8-10x, then you can start to see what they might have accomplished. Then again, they didn't need computers to remember things for them, either.

We've know small steps are doable, as we're seen them done. We know of no mechanism that would prevent small steps from accumulating into large changes, and we've evidence that supports prior large changes. We have a mechanism for it to happen that we know happens, we have no way of preventing it from happening, we've seen what appears to be it happen, and we have no alternative hypothesis with any believability or support at all. If that's not good enough to be considered "proof", then nothing will be. *Nothing*.
You seem hung up on some simplistic theoretical Popperian model, one so simplified that even Popper wouldn't subscribe to it. (Finding evidence of alternatives that deny the hypothesis would disprove it, so something can be disprovable even if it's not testable.)
All of astronomy, for thousand of years, has been done this way. Do you think astronomy's not a science?
