I have a friend who is a serious flat earther.
It's hard, he actually has a thought process, which I really do believe is a rare thing these days.
They have an answer for everything, and I mean everything. I had a chat with him about seeing a big ship come over the horizon....this was his response:
You did see it over the horizon in your mind. That is what you know. Truth is that water
is always level and can not stick to a spinning ball. What happens when you see things in a distance over water
is that you see the top of the ship first. Lower to the surface or the sea you will have more water vapor so naturally you can not see so far through the thick vapors. Less vapor and you can see further.
So, as you can see, an answer for everything. And to be honest, they do actually come up with some interesting points.
My wife and I now laugh about "rounders" . It throws folks off when we laugh at folks for being a rounder in front of them. All in jest of course.
And, to your question about sailing....yes they have an explanation for that as well.
Interestingly, my mind moved from if the world is flat then the whole round earth lie is being pushed upon us. By whom? And to what end? I asked if he believes in aliens......well, that was the wrong question to ask. Would not discuss it, not so much as a peep.
I think that his wife has drawn the line at flat earth.....aliens means divorce.
All very intersting. Like I said before though, I admire that he does seem to have synapses comunicating in his head
unlike the flatline happening in most heads these days.
Be offended if you like, it's ok with me.
