@Silverchild79,
America would have been found sooner or later, you just don't permanently misplace such a large land mass. Columbus was one of a half dozen people to find the Americas, there are Icelandic relics recovered on Newfoundland annually.
Eventually the Greek/Roman Pantheons would have been put down. With the advancement of science more and more of the Greek religion would have been put aside (IE nobody with today's education would believe the sun was Apollo's fiery arrow, and storms at sea are understood today to be climate driven not the wrath of Poseidon). Similar arguments emerge today concerning the age of the earth, the 10 plagues of Egypt, the great flood and many other topics. Sciences ever reaching grasp is beginning to comprehend things which only 100 years ago were still being called miracles.
