Also, our scientific models work well for 90% of stuff - that doesn't mean they reflect the whole at all. Newton thought gravity was a force, Einstein a warping of spacetime. Newton was right - to a point. Was Einstein right - to a point? I'm not a physicist, but I am a scientist. If we accept there are 'aliens' - a lot can be learned in 100 000 years of civilisation. They could be a billion years ahead of us.
