Creatures went from giant to tiny, and people went from smart to stupid.

Most people yes.

That is what we call Gen Alpha, or "brainrot".

And, the context regarding to creatures, is because of evolution! In the prehistoric era, scorpions and beetles used to be the size of a large dog, and as time went on the evolution went to a reversal somehow and that's how we got small bugs. It's sad.

The Earth's history is pretty wack like that, honestly.

Yeah.

I made an infographic about Earth's history, BTW :>
