how people swim in water

Question

Hi guys I never learned to swim as a child, and I’ve signed up for adult swim lessons soon. Something I think will help me prepare for the lessons is I don’t know the mechanics/physics behind the motion. So I’m asking

1.) how do people float in water and why is it crucial to swimming?

2.) how do people actually move from point a to b in water while swimming?

EDIT: thanks so much to all who have responded with answers, tips, advice, and encouragement! Trying to read through all your helpful answers ☺️
