"Ad Hominem" just means you are insulting the person rather than addressing their argument. Like, calling someone stupid, instead of explaining why what they're saying is stupid.
The only time I ever got in trouble playing with those things was when I was having so much fun, I didn't notice a line up of people started forming behind me. They were all looking around wondering who's fuckin' kid this was.. My mom got so embarrassed she dragged me away by my hair, and told me I wouldn't be allowed in the bowling alley anymore if I couldn't act normal.
That's actually not true. Even steel girders will dissolve to rust within a few hundred years, if left to the elements. Fossils are a 1 in a million occurrence that require precise conditions in order to happen. In conditions that are less than ideal, there would be zero evidence of anything we have built in the last few thousand years without constant maintenance.
Only stone endures long enough to last longer than that, and we tend to harvest stone to build new things, every time we find old things made out of it. So everything that would have otherwise lasted, could have easily been recycled so many times over, that it's completely unrecognizable now. Except for the few, rare structures that we see today, and have little to no explanation for, other than speculation based on vague 3rd person accounts.
We don't. But I find it hard to believe that not one person in 90,000 years of human history, never came up with a single advancement similar to the ones that happen all the time now. Our brains were just as developed as they are now, for that entire time.
It is inconceivable that we only started using them in any significant capacity, just recently.
Human beings have been around, in their current state of intellectual capacity for well over 100,000 years.
Looking at all that we've accomplished in just the last 10,000 years of known history...it is not unreasonable to assume that we could have accomplished just as much several times over already...but for whatever reason the knowledge of those accomplishments have been repeatedly erased from history.
That sounds like something a radical left antifa terrorist would say.
