A new perspective the best 3D geometric shape to will last in space is a spher

Let us think about a planet being in space for 4.5 billion years, like earth. For a planet to survive being hit by debris or meteorites it needs to have a shape that can take hits by really large objects. If the earth was flat and was hit head-on by a large meteorite it could potentially break in half. It is a very bad shape to have floating around in space because any shape with corners or edges will have weaknesses. A 3D triangle which is a very strong shape can be weakened if you hit off one corner or an edge. A spherical object can be hit from anywhere and stay intact as it has no edges. A blow from anywhere can be disbursed over the surface more evenly. Also, if space debris keeps hitting an object in space that had any other shape than a sphere, the debris over time will turn it into a sphere as all edges will eventually over billions of years be smoothed out, especially as the earth spins. A flat disc would be bombarded over time and the edges would break off, or the disc could break right in the middle by a huge meteorite. There are no known planets in space that are like a flat disc, so why would the earth defy
 the laws that apply to the rest of the universe? As no one has seen the back side or the actual edge based on the F.E.T. that there may be one, they have no idea what is there. Maybe it is hollowed out and the earth could split at any moment?

The only shape that can stay in the universe and be bombarded over a vast period of time by space objects would be spherical, or it will eventually become spherical by all the debris. Take a cube made out of soapstone (soft stone) and make it spin on an axis, then bombard it with sand, sandblasting it for a long time; it will end up looking like a sphere. If you do that to a spinning disc, the edge will be blasted off until eventually, it would turn into a small ball, about as big as the disc was thick. I propose that it is impossible for a disc to stay a disc for 4.5 billion years as it spins its way around the universe. And by the way, the strongest #D shape there is is a sphere...

But there are non spherical objects in space, like asteroids for example. If what you say is true, and that all non spherical objects become spherical over time because of collisions with debris, then these asteroids could not exist. But they do, which means your analysis is flawed, and does not provide an explanation as to why the Earth is a sphere.

OK. well, u r so stupid, learn quick maths :-X :'(

space? billions of years? smh.
start with simple things that you can verify..  not assumptions piled onto more assumptions..
