The Mars Problem
Scientific research by NASA and SpaceX indicates that it would take a minimum population of 98 to 110 people to populate Mars, therefore the Noah's Ark story never could have happened.–An Atheist
Initial Response
In the paper Joseph Chang 1999, it is claimed that the MRCE of all human beings is no older than 5,000 years old. This comports with the idea that an event happened that caused us to all descend from the same father no more than 5,000 years ago.
Atheist Response
The paper that Joseph quotes doesn't actually say that, and it is unclear how he drew that conclusion.
Discussion
The paper might be this one: https://www.cell.com/ajhg/fulltext/S0002-9297(13)00073-6?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0002929713000736%3Fshowall%3Dtrue
The conclusion so far is that the atheist who brought this up doesn't know what he is talking about, It seems at the minimum he doesn't understand the difference between genetic and species MRCA.
