The OSIRIS-REx spacecraft, which "arrived" at the asteroid Bennu on December 3 but has been slowly approaching it for weeks, has found evidence of Bennu's interaction with liquid water in the past:
In a conference today, scientists announced that OSIRIS-REx has found evidence of hydrated minerals on the surface of Bennu using its on-board spectrometers - tools used to determine the exact chemical composition of a specific spot.
That means "evidence of liquid water" in Bennu's past, according to Amy Simon, the scientist overseeing OSIRIS-REx's spectral analysis.
"To get hydrated minerals in the first place, to get clays, you have to have water interacting with regular minerals," says Simon. "This is a great surprise."
And they're abundant, too. There's "strong convincing, evidence that the surface is dominated by these hydrated minerals," according to Dante Lauretta, leader of OSIRIS-REx's sample return mission, leading the team to believe Bennu is "water rich".

According to standard ideas, the orbit of the asteroid cannot be traced to an origin on Earth; indeed, any such impact large enough to hurl material of that amount would not produce a large, cohesive chunk anyway.
Your idea is fun, but it appears to have no basis in the way the universe works, as far as we know.
