no thats imposible..

Why would it be impossible ? We hardly know what lies in our ocean, how would we know what lies beyond this planet ?

because I had never seen it

How about god, do you believe that he exists ?

I certainly believe in the existence of god ..
because obviously what he has created in this world

Well, you believe in the existence of god, yet you haven't seen him. Believes are what makes us humans

Imo, we can't disregard everything which we have yet to see in our own eyes.

We can't see science but it explains a lot.
Math and physics are the key here not your eyes. Wink

If they're out there scientists and engineers will find them.
