Your sensory organs only transmit "input." It's your brain that interprets those signals. That being said, your brain interprets what it sees based on what it expects to see.
So if you were to ever come face to face with something truly alien, would your brain even show it to you?

What about when you are born and everything was alien to you, we still saw it

Depends
Humans are toddlers in comparison to what exists.
We can only perceive a few colours
We only have 5 senses
It would depend on if it met our criteria.

We see aliens in movies dumbhead

Yes, it would. But it would look for recognisable patterns. If it couldn't find any then it would go "holy fuck what is that" and tell you to run.

how alien?
it reflects light, doesn't it?
it makes noise, doesn't it?
it smells, doesn't it?
why shouldn't we see it/feel it?
