Inquisitive should study basic physics to comment on these subjects. It can be confusing without a solid foundation in physics to understand this subject.
It's funny you say this because I used to write the complex codes for softwares that physicists used and in fact you don't need to be a physicist to debunk this whole ball earth myth.
This same line of argument can be used against you regarding evolutionary biology to refute you on everything, it's simply an insincere argument.
Even if we applied this argument, there would be no such thing as atheist or a ball-earther etc. because in order to believe in these occultist myths you will need to be very well grounded in biology, physics, chemistry, cosmology, astrophysics etc. virtually impossible in this short life-span, even the occultist don't achieve this.
I like to take a pragmatic approach to this subject, relying on my own observation, logic, senses and critical thinking, not blindly rely on the occultist that are so called purported experts in those single individual disciplines.
I look at something like gravity, the supposed mythical force that even acts upon me while I ride a bike or take a dump in the toilet, a force that supposedly holds a trillion litres of water on a ball earth for which the smaller moon object control's it's tide, overpowering the supposed gravitational force of the larger body (Earth) and laugh at it, the whole thing is a ball of contradiction.
I then look at the natural physics of water of always finding it's lowest level, I can carry out this experiment anywhere in the world and the water always flows in all directions until it finds it's 'lowest' level were it will settle e.g. 'sea level'
I look at the all the great rivers in the world and they all flow down wards to the sea, I then look at a pond of water or a small lake, no tides no supposed gravitational forces acting on them from the moon, but only on the much bigger rivers/oceans, this is simple logic to refute gravity and I can go on for pages upon pages with this.
You on the other hand accept what you have been taught and cannot see beyond that paradigm nor think, you put a lot of effort in defending this myth because you used it to argue against the atheists that claimed the Quran states the earth if flat, I understand the conflict of interest your having bro, either bring something of substance or sit on the side lines of this karbaash.
