So I was wondering if anyone has ever tried with success to determine an average amount of space debris that comes into contact with planet Earth over a set amount of time. Such as atom, molecules to meteorites. I'm guessing it's very minimum during this part of Earth's history, though I'm curious.

It would be burned up in Earth's atmosphere.
I know that this does not help, but meh...

1.5E8 kg per year. That's 150,000,000 kilograms per year.

which is an incredibly small fraction of Earth's mass, i.e. total dust accumulating on Earth is 2.5E-17 times what Earth's mass is.
