Why is there stuff? this is a science question?

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
