I have always wondered: since the dinosaurs became extinct until the first man appeared, millions of years have passed, could there be any other intelligent species that we don’t know about?

Brain development in humans is related to hunting and development of simple tools. And then of course, there’s my favorite “stoned ape” theory, that eating psychedelic mushrooms was the catalyst for our rapid expansion of intelligence.

It seems that the evolution of the species is too slow 🆚 the distances in the universe. Maybe that’s why we don’t find intelligent life in the universe yet. Our species will probably end up extinct before finding intelligent life on another planet.
We need to eat more psychedelic mushrooms.
