Question: Why are we alive?

Verity Hill answered on 11 Nov 2018:

All living things live to pass on their genetic information to the next generation!
We all have genes, which are packets of information that govern what we look like, and how we do things. Everything living things do is to increase the probability that we will pass on genes, by surviving long enough to have children and then having them.
For example, humans walk on two legs probably so that we could hunt large animals better so we had more food so that we could have more children. Bacteria develop antibiotic resistance because this increases their survival (especially compared to ones which don’t!).
