If man has been around for a million years and presumably getting at least a little action, where are all the people at? The Earth would really be crowded, and you'd think filled with a lot of bones somewhere? There is no evidence of either.
You can find out for yourself using secular resources only that if a handful people started having sex with one another around the time of the Biblical account of the flood, there should be about 6.8 billion people on the planet.
These non Christian sources, statisticians, anthropologists and experts in the field of demographics have calculated these numbers. Taking in the effects of disease, wars, famines and cultural beliefs that in 1820 there should have been about 1.6 billion people on Earth. In 1920 there should have been about 2 billion people, in 1970 there should have been about 4 billion people, and today there should be about 6.8 billion people. Wow, you'd think some Christian would have fudged these numbers there so accurate. They also figure by 2050 there will be about 9 billion people on Earth. (Unless the Duggars stay married, that might skew their numbers quite a bit?)
So once again, if we've been here so long,(750,000 years 0r maybe a million) where's everybody at? Do the math yourself, you think the line in McDonald's in long now?
Peace Out, feeno
