Question

Why is there stuff? this is a science question?

Answer 1

This is a strange way of asking a question but "stuff" is  made up of things called atoms. EVERYTHING is made up of atoms. In solids, the atoms are tightly compacted together. In liquids, the atoms are sort of close together but move freely. In gasses, the atoms are very spread out. I hope this answers your question, I can't really think of much else to say about this... :D

Answer 2

Stuff are matter. Matter is anything that has mass and takes up space.

Stuff, like tables etc, are all matter. Because they all take up space and have mass.

There are stuff because we would not live without materials.
