If you go back in the genealogy you cannot go back further than Adam and Eve, who were not born.
If you took a child born 30,000 years ago and raised it in a modern family, basically you wouldn't be able to tell the difference between it and a modern kid.
If you went back 70,000 years ago you might find it difficult to find a kid to borrow because the human population dropped to its likely lowest value of about 1000.
Go back 185,000 years ago. Now you can have a discussion about whether you are dealing with modern humans or an ancestor species. Evolutionary change is slow and species boundaries are not crisply defined; arguments can be made for the appearance of modern humans tens of thousands of years either way depending on your criteria.
We are the products of continuous successful reproduction of a line of descent that stretches back to single-celled organisms, some time over 500 million years ago.
So, there is some of the timeline laid out. I've left out some details! Of course I didn't do the massive body of careful, painstaking work that has established these as facts of natural history, but I certainly respect it as reliable knowledge with the usual scientific requirement that it remains open to alteration as new evidence comes to light. Almost always, new evidence makes subtle adjustments to improve accuracy or add detail. No one has yet discovered evidence that brings the whole timeline into question.
So, your turn. This claim of yours that there is a human genealogy that stops with two humans who weren't born.
1. By what biological mechanism are humans made? (I note the bible lists at least 4 different ones).
2. At what period in the past, to the same sort of accuracy I have given in my claimed timeline, did this sudden emergence of two humans happen? (±20% should be enough error for either of us).
3. Why does the fossil record clearly disagree that there ever was a time of only two humans?
Bonus question:
4. Did this created pair carry with them all the human-specific parasites, to be passed on to their descendents? If not, by what mechanism have humans come to have human-specific parasites?
I think if you can't answer these questions convincingly then there is no reason to pay much attention to your claim, or to any similar claim by creationists anywhere.
