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 ?
How about god, do you believe that he exists ?
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.
