Sorry im a new flat earther and i had a thought about tectonic plates so i would like to learn and if tectonics dont exist then what are Earthquakes?
What makes you think tectonic plates don't exist?
Tectonics may not exist because it is a habit of flat earth thinking to deny the existence of anything that disproves (or cannot be proved) by the obvious truth of a flat earth.
John Davis may answer by saying flat earth researchers don't have the funds to research what plate tectonics actually are.
I personally don't think any flat earth proponent has given plate tectonics any thoughts so it may be a while before you get a flat earth thought experiment on this.
