You know, it is very dfficult to believe in what you don't see. However, this world has been made in a manner that you simply have to trust more in what you don't see than in what you see, at least if you want to have peace of mind.
Who has ever seen the deepest ocean bed? how do you know whether the moon you watch is not a big light put by aliens to spy on us? Why should you believe that the earth moves around the sun and not vice versa? If scientists say that we evolved to better beings, why didn't monkeys and apes and protozoa do so too?
I cannot prove that space is real but I know its there, just like air, earth rotation and yes GOD!
