Biblical lifespans seem nice, but only if you wholly believe the stories. Given how often the same stories come up across different civilisations, I'm sceptical they're accurate. For instance, Eve picking an apple is not too dissimilar to Pandora's box. The flood in Noah's lifetime is also part of Babylonian myth where the protagonist was Gilgamesh. I recall even the concept of hell was taken from Greek mythology - notice how we call this mythology today instead of religion.

Answering questions like "where did we come from" and "where are we going" have always existed. Passing knowledge down through generations has always existed. Treating these stories as gospel makes little sense to me.
