Basically I was outside jogging this evening.
Bear in mind, this is a question which has plagued me for a big while now.
At the same time, I consider myself a fairly smart guy for my age. However, I could not explain this very basic everyday phenomenon.

I'm really interested in science, and I am very much into attempting to explain planetary occurrences.

So, can anyone explain to me why, if one side of the Earth is lit up by the sun while another is in darkness, when it got darker while I was outside jogging, I didn't see darkness come, but rather light was becoming less and less?

Have you seen rain? It is possible for you to stand outside a rain cloud, on dry land, and observe how the rain falls from a cloud a short distance from you?

So why is this not the same with light, if the Earth were round and one part is in total darkness? Why don't we see the darkness travel towards us ever? We just see the light get darker and darker and more snuffed out, but we see no darkness coming towards us as though rain would come from a cloud while we stand in the dry (or the light in this case)?

Also, could this be a fair argument for the Earth being flat? Mind you, I don't believe in that flat Earth BS, but the only way the night would come the way it does is if the Earth was, in deed, flat.

First off. Darkness is literally just an absence of light. Nothing more, nothing less. You can have a flashlight but nor a flashdark. So of course you only see fading light. If you're asking why you don't see some sort of wave of pitch darkness coming over the horizon at night, its because everything is really big and happens over hours. You cant really point at some light level to call "dark". Nor will you perceive it as some looming wall as it occurs gradually over hours.

Good observation. You will also notice the light won't disappear all at once, rather it follows the sun as it gets further away and doesn't take up the whole width of the horizon, which it would if 93 million miles away.
