I don't see monkeys unlocking the secrets of space anytime soon.
I don't see you unlocking any space secrets either, at least a monkey can survive on its own in the wilderness.
Monkeys are a couple thousand evolutionary years behind humans.
It will take them a long time till they can reach us. They should have evolved like us humans did but decided to stay as monkeys.
Evolved differently =/= better or further ahead, evolution is adaptation to our environment in order to survive, monkeys are doing just fine. If we use the generally accepted idea of "more evolved" meaning an older and more complex genome, then a grain of rice is twice as evolved as you are.
We like to think we're great and all but really we're just more animals that think we know better than the rest.
To quote one of the most epic works of poetry to date;
“Tiger got to hunt, bird got to fly;
Man got to sit and wonder 'why, why, why?'
Tiger got to sleep, bird got to land;
Man got to tell himself he understand.”
― Kurt Vonnegut, Cat's Cradle
