Oldest stone tools ever found not made by human hands. The tools, made by one of our closest homo relatives date from 2.6 - 3 million years ago.
Seems we weren't the only tool makers way back in the day..
We aren't the only ones now either.
Once had an evangelical tell me that the only reason we think carbon dating tells us things are older than 6k years is because "Noah's flood rearranged the strata of the Earth's crust". It was so many levels of dumb I didn't know where to begin.
