Who was the second person born?

It's impossible to know who the second person born was. We don't have historical records that detailed that level of information from the very beginnings of humanity.

Here's why:

* Early human history is poorly documented: Our knowledge of early human societies is based on archaeological evidence, which doesn't usually provide personal details like birth order.

* Many early human populations didn't keep written records: The concept of recording births in the way we do today was a much later development.

Even if we had records from that time, we wouldn't know the exact order of births, as multiple births (twins, triplets, etc.) were likely to occur.
