How is it that pyramids were built in Egypt and South America at around the same time? Coincidence or something more to it?

They were not built at anything like the same time. Is it any more puzzling that two civilizations decided on the shape of a pyramid than that they decided on a square or a rectangle?

It is perfectly possible that the natives in South America knew about the Egyptian pyramids, which had been around for 1000 years. People DID travel, including crossing oceans.

Some people think that ancient egyptians reached this land long ago..one explorer trued to prove it and did a long journey starting from egypt using simple boats

They weren't. The pyramids in Egypt predate Christ. The pyramids in South America weren't built until close to a thousand years after Christ's death.

I think there is something more to it. It might be coincidental, but I have other thoughts.

Give or take about two thousand years. Yeah, right.
