Well, are we, as human beings, omnicient? omnipotent? Both? Neither?
I believe that we're not even clairvoyant, much less omnicient. I mean, look at history. Hitler (overused example, I know) definately did not know anything. Former President Bush? Um... He knew more than we know, but that's just my point! WE, as humans don't know everything.
In answer to the second question, omnipotence is completely asurd. I mean, if we were omnipotent, would we not have stopped, say, pollution? wars? Would we not have cloned extinct species because of our extreme curiosity?
If you disagree (or agree), please find the holes in my statements. Lawyers do it all the time!
