Probably not all of us know, but continents were closer, very closer in the beginning of the time. Regardless of what we believe or not, massive landscapes will be submerged and part of continents be distanced. This may sound like a scary story from a story book but constant tectonic plates movements would eventually cause this. This is how earth maps would look like in 100 million years. Skeptics can have their disbelief but I wouldn't, given that certain rise and fall of heights in Kathmandu Valley and Mt. Everest region that took place recently after that major cataclysmic earthquake on April 25th, 2015, it's obvious Earth's map is on constant shift.
