The "smarter" we humans get, as we inspect and dissect ourselves and our natural surroundings, the more difficult it should be for us to dismiss the evidence of an intelligent designer behind it all.
It would be much easier to believe all of this could have happened by chance, if it weren't so extremely complex.
Occam's Razor directly disputes your assertion here. You add complexity to the issue by adding a designer. There is zero evidece of intelligent design.
