I grew up in a Catholic Italian family in Canada, so I'd never heard the earth was flat.

I did learn that spaghetti was not invented in Italy, and THAT was shocking.

*sniff

Before school age my parents had bought us both a globe and a wall-map. Looking back it was a satire of their religious upbringing, they told us it was for us to decide which was right and left us to it. It might've took a couple of years but I figured out in the end that while a globe was nonsensical and maps quite normal, the ends of the map didn't seem to make sense, the way they magically continued again on the other edge. So I just lost the plot and asked for a giant turtle for xmas.

Probably pretty early. I was an inquisitive little one. I followed space launches and was aware of Mariner 4 and the ranger missions when i was 7 so I certainly understood well by then. I watched a puppet show about rockets as a little kid called "Venus and Steve" as I remember. I don't know how old I was but I knew while watching it that the Earth was spherical and that the moon was another body with a surface. I think I was in 1st grade then but I think I understood that the Earth was round well before then.

The early space program is pretty murky for me. I thought I was aware of Luna 3's first photo of the dark side of the moon but that is not possible as I would have been 2 years old. I followed the Gemini program extensively. Apollo was my early teenage years.

I'm pretty sure I was learning about perspective missions to the moon and how astronaut's might get there before I stopped believing in Santa Claus. I remember spending a Christmas eve with my Great Aunt and reading the book on the moon mission plan and then wondering where Santa was in the sky and if I could see his sleigh while we were driving home.

I think I was smart but very gulible...

I grew up being taught that the world was round I never ever thought that the world was flat

I think I saw a globe, like, always

Wow. I was never taught the opposite.

Day zero.... like before I was born.

Don't think I ever thought it was flat. But distortions on a world map always mess me up. Never thought gravity was magnetism. I asked why we were not hurled into space when I was younger.

When Santa Claus told me & took me for a ride. Yes ........LSD

Not sure I ever thought it was. When I was five years old, I got to watch the moon landing (Apollo 11 mission) and return to an obviously spherical earth, complete with splash down.

Had a lovely globe in my bedroom as a kid. I don't honestly remember thinking of the world as anything other than round.

I have no memory of ever thinking it was. My biggest like was when my further learning caused me to see that it is an oblate spheroid instead of sphere, yes early educators use that word.

Never thought the Earth was flat, when we learned that some thought it was flat during the middle ages and before, I remember thinking "How archaic, where did that idea come from?".
I have never thought gravity was electromagnetism, I found out through reading that it was a fundamental force. For a long time I thought electromagnetism had to involve a battery. I learned better.

I never did think that the earth was flat. I didn't realize that there are people that actually believe such nonsense till a little while ago. I think that the encyclopedias will have to add more to what of is real and what is not some silly nonsense.
For the life of me I really can't fathom just how far fetched stupidity can go.

There was no "realization". It just is.
Why on Earth do people have to make so much so bloody complicated?
It's NOT that hard.

I don't remember it ever being flat. I do remember that Christians killed people for saying its round at first.

Idk, pretty young. Globes were standard in elementary school.

I don't know what electromagnetism is, but I never once thought that the earth was flat and before I heard the word gravity, it was clear to me as a young kid that if I threw something into the air above my head I had better be prepared to catch it or move out of the way.

What? It isn't?

Bugger, That's another belief dashed since I joined this site....

Is nothing sacred?

I don't ever remember thinking is was, I wasn't taught that is was and nobody I knew thought it was either.
And if there was any doubt, this can't happen on a flat earth

It's not?

We had a globe, and I just accepted that as the shape of the world. As a toddler I don’t think I bothered with such thoughts one way or the other.

Really? Is it not flat? ?

Never thought it was.
