Answer:

Nitrogen/Carbon/Oxygen/Hydrogen

Explanation:

I believe those would be the most important because:

Nitrogen - Composing 78% of earths atmosphere.

Carbon - Building blocks for all known life.

Oxygen - We breath it as well as it composes 21% of our atmosphere.

Hydrogen - Makes up a bunch of compounds (like water) that enable humans to live.
