i know we came from monkeys but where did the monkeys come from?and what was the first living thing on earth and how did it evolve?and also more than 50% of the earth is water so where did the water come from?when earth was created, it was just land with lava so where did it come from?some say the water came from ice from meteors,but you need water to make ice so where did the ice come from.others say the steam from the volcanoes turned into water but, you need water to make steam,so where did it all begin?
