How are atoms made

All the material objects around you are composed of submicroscopic units we call molecules.And molecules in turn are composed of individual atoms.Molecules frequently break apart and then form new molecules.On the other hand,virtually all the atoms you come in to contact with through the course of your life,the ones in the ground beneath you,the air you breath, the food you eat,those that make up every living thing, including you,have existed for billions of years and were created in places very unlike our planet.How those atoms came about is what I want to share with you.
