We have relatively primitive brains after only a very short period of evolution... about 300k years. Scientists estimate, using such things as the Drake equation, there may be approximately 10,000 intelligent civilisations just in our own Milky Way galaxy. Never mind in the universe beyond our galaxy.
Many of these civilisations will have had millions or even billions of years of evolution. To them the human species are about as intelligent as ants are to humans!
Bottom line is that we extremely arrogant if we think we know how to even formulate the right questions, let alone exercise our pea-brains to find answers to the really big issues!
Might as well ask your cat!
