We have no evidence yet, but we're living on this planet for so long and we still don't know everything about it yet. Think about our level of knowledge of our own solar system! And then the rest of our galaxy & the universe. Just because humans don't have an evidence, doesn't mean it doesn't exist. We just haven't found it yet, considering the sheer infinite size of our universe (probably infinite) we'll never be able to know everything. It might even be possible that we never even find intelligent alien life forms. But the probability of them not existing is way lesser than the probability of their existence.
