I was going along with your scenario just to be pleasant, but by now I've lost all interest, sorry. In reality it's obvious that nothing could have lived where the sediments were deposited over thousands of square miles that became the strata in the Geological Column. Nothing could have been living already from the previous deposition, and nothing could have evolved from anything previous for that reason and even if something did live it would have been buried by the next deposit. Thinkity thinking should get all that across.
I thinkity think that you refer to an alternate reality and your only reaction to Stile is denial.
Not very respectful, actually.
