Someone please uage my doubts about Pangea.?

I am a solidly scientific-minded person, but I have long been uncomfortable with the Pangea theory. Sure, we have continental drift and it gives a good indication of how the continents are spreading, but what would have caused all the land m to form on one side of the earth and then break up like it never should have been that way in the first place? What caused the bulge? And why would all of this spreading have occurred so recently, geologically. It seems to me that this would be a good creationist objection to evolution: so many species having such recent common ancestors on this big, single continent? Then it broke up and was separated by oceans? I haven't heard fundies use this objection yet, but I'd like to know, myself.
