There are a couple of reasons, I'm not just limiting my thinking to the pyramids, but there are many more monolithic structures in the world besides in Egypt. Many say it was because of their engineering and astronomical abilites that gave the Egyptians the ability to build the pyramids. Did other cultures have that same ability where we find additional unexplained monolithic structures? It just doesn't add up, how were all the records destroyed in so many places, and what happened to that knowledge? Surely if they were smart enought to build the things, they would have been smart enough to keep records of their work. Where did the statues come from on Easter Island? How did they get there and I can ask many more questions. I do not believe in aliens, but I do believe in fallen angels, and they most definitely would be able to do these things. I can't see how this is so hard to grasp, to me it makes complete sense, much more sense than Seth's line and men building these things. I can't convince anyone, but in the same way, I can't deny it, I'm convinced it is true. The people I talk to about it seem to grasp it and agree, so it isn't that far fetched. Keep in mind, this does not harm the gospel or anything, just a curious question to ponder.
