If human beings are hybrids designed here on earth why aren't we more scientifically evolved if we started here 65 million years ago?

 It's because we had to survive ice ages which are caused strangely enough by Global warming times like now. If you speak with a PHD in Climate Science they will tell you that Ice Ages start in Global Warming. Though it is believed that the planet just gets hotter and hotter this isn't usually true. At a certain point it goes the other way into an ice age. The undercurrent of series like Snowpiercer are trying to inform mankind about this problem because most people don't seem to understand that an Ice Age is likely where we are presently headed (if we don't die off from overpopulation and the 6th Great Extinction first combined with the effects of Global Warming which are increasing yearly at this point.

It's important to understand that the North pole once averaged 76 degrees Fahrenheit year around to tell you what might be coming for us before the next ice age by the way.

So, weather extremes likely are why we are not more scientifically advanced than we presently are after living here ongoing from 65 million years ago.

When you go from 76 degrees Fahrenheit average even at the north pole to ice down to around Mexico Worldwide in ice ages at that latitude human civilization likely hasn't fared that well in cycles over the last 65 million years of our existence here on earth.

In other words both climate and geology through earthquakes and rising and falling seas can change a lot of things in regard to humans of earth in addition to bad governments and crazy people sort of like we are dealing with now who are living in denial of coronavirus and are dying like flies from it while trying to overthrow the government while believing in lies because of crazy people like Trump.

So, we might be looking at future Cave man and cave women times unless we get it right this time too.

It's all up to us. Will we go completely mad like Trump and his followers or will we be logical and reasonable like scientists and live on through whatever comes here on earth?

A big part of the Madness of Trump and his followers is that they can't get past denial of coronavirus to a sane, logical and reasonable way forward. And because of this they are self destructing en mass right now

and taking many logical and reasonable vulnerable people with them.
