It's not that something is "stopping us from getting to know god", we just simply contend that a higher power doesn't exist at all. When you die its lights out. We're just like any other organism on earth, we just go to sleep fooooreeeverrrr. There is no evidence for a god or any of the magical things he did so long ago. All the things you've seen that have made you convinced there is a god have happened by chance.
If this all powerful all loving being could do anything whatsoever why would he let cancer, starvation, or any agony happen to his "beautiful creation"?
btw I got a couple questions for you....
How was that a quick question?
and
What's with the "G-d"?
