Atheism

The law of gravitation existed even when it wasn't discovered.It existed even when it was being discussed and denied by many.It won't cease to exist even if we forget it a hundred,thousand or million years later.

So does God.....

You take a finite amount of time say an hour,two hours or how much ever to learn a particular academic fundae.A lifetime you say is not enough for people to understand you.You,sometimes feel you cannot comprehend yourself.It takes a lifetime to know things,people and anything around you and not without continous effort.But,you expect to know,understand,feel,see,touch God with no effort or little effort.Failing which you deny His existence and claim to be an atheist.
Whose fault is it?
