Part of this argument is scientific. Anthropologists, for instance, might tell you that human beings began to evolve from apes around 4 million years ago, with the first homo sapiens neanderthalis said to have evolved from homo erectus around 500,000 years ago. Of course, these are estimates that changes periodically. On the other hand, geneticists might also argue that the "genetic Adam” lived either sixty thousand years ago or as far back as 150,000 years ago, which is the era they have traced to the "genetic Eve.”
Catholics, on the other hand, might argue that Adam lived approximately 6,000 years ago. At least, that’s what the religious scholar Bishop James Ussher discussed when he published a calculated date of Creation to be October 22, 4004 BC. At the same time, other spirituality experts might suggest that Adam and Eve lived several thousand years before that.
One problem posed by the Judeo-Christian argument about Adam being the first human, though, is that other creatures are described in the Book of Genesis. In the Bible, discusses that God made Man on the 6th day and placed him in the Garden. Some experts argue that this means there were other humans outside the Garden; which is something that is actually discussed in the Bible, particularly in regards to Cain’s banishment. During this passage (which is only the fourth chapter of Genesis) the speaker talks about how "any finding him should kill him,” which suggests that there were other humans besides the "first family.”
