And who says...
...that if there is a god or a creator of this Universe, that they are
perfect or omnipotent or supernatural?
Theoretically, "baby universes" could be created by crushing matter to
a very dense point. If we can at least conceive of this, who is to say
that an advanced society has n't already done this, and we are one of
the results of their experiments in this field.
The theory also states that once these new universes are created,
they are "snapped off" from our existence and neither universe can
communicate with the other.
So perhaps the Deists have had the right idea all along: A Universe
created by a being who wound it up like a clock then just let it run
by itself while he went off to watch TV or some such.
