Based on what evidence?
And, what do you mean by “people”? Homo Sapiens is but one specie of “people”, and the evidence is mounting that “we” have been here a lot longer than Judeo-Christian beliefs will tolerate.
As SWMBO has been preaching for decades, there is much more evidence that (e.g.) Neanderthal DNA was incorporated into Cro Magnon, et seq. than the popular Xenophobic “extirpation” fantasy. (Q “What happened to the Neanderthals?” A “We’re still here!” Q “What about the Cro-Magnons?” A “Us too!” “Friggin’ illiterate Cro-Magnons!”)
Sorry, but it is not difficult to discriminate. This is what it looks like to “examine your beliefs” and maintain a sense of humor. Trust me, it isn’t fun! It won’t win you any friends or influence many people (of any species)! But it’s like the old cliche, “Once you see it, you’ll never be able to ‘un-see’ it!”
(Hint: the same rocks were there, then…)
What difference does it make whether you die or not some day? What matters is what you do with THIS day. If I can prove that, is it still a belief?
