Just dabbling in general science might help.

Look at that tree. Where does it come from? A bunch of random atoms somehow decided to make a tree. Out of what? If we burn a tree, all we get is a little ash. That ash is the only solid chemicals that the tree pulled out of the ground. What was the rest made of? Where did it come from? Photosynthesis tells is that it came from the air. 90% of every tree is just conjured from air.

We’re surrounded everywhere by crystalized air.
