If continental plates and oceanic plates are moving around aimlessly, why were the continental plates ever all together to begin with? Isn’t that as unlikely as a mixture unmixing?

Answer 1

They weren’t necessarily altogether to begin with. There was just certain times of which when they did come together ie: Pangaea.

I mean originally the earth was too hot and constantly being bombarded by asteroids and meteors and so coudlnt form an atmosphere or oceans.

Edit: also like the last user said it’s not really that unlikely when you consider the Earth is over 4 billion years old. By contrast human civilization is like 7000 years old max. A fractional amount so small its basically 0%.
