You grew up prior to 1920?
That's when it was first proposed by a [then considered] nutcase. Yeah...the 97% blew him off.
From Wikipedia:
David Attenborough, who attended university in the second half of the 1940s, recounted an incident illustrating its lack of acceptance then: "I once asked one of my lecturers why he was not talking to us about continental drift and I was told, sneeringly, that if I could prove there was a force that could move continents, then he might think about it. The idea was moonshine, I was informed.It started to gain adherents in some circles in the 50's (I was born in '52) but I was flat out told by my elementary school teacher that my theory that South America looked like it could fit into Africa (a theory held by every child that ever looked at a globe) was wrong and it was "just a coincidence".
It was not until 1968 that it became the dominate thought.
Just remember that when Global Warmists pound you over the head about "settled science" and the 97% "consensus".
