What makes life?
Wow! You may have hit the jackpot with this one. Nobody knows what "life" is. They talk about living things, but how did they become "living"? A bunch of chemicals getting hit by lightening? Pretty stupid idea. How would that create "life". How many puddles would dry up? How many would get hit just right How would electricity create life in the first place? Why doesn't it happen all the time? Well, it doesn't. And electricity has nothing to do with it. Life seems to be some sort of energy that is passed from one living thing to another. Things can only live if they get that energy somehow. When someone dies, the energy is gone forever. Where did the original energy come from? Nobody knows. Where does it go? Nobody knows. What is it? Nobody knows. You can zap puddles of chemicals every day, you can create the most complex android that simulates everything a human can do, and it won't be alive. If life is easy to create, it would have been created in laboratories around the world by now. Scientists have been replicating early earth for decade and zapping it with everything they can think of. No life. That may mean that there is no other life out there but right here. Maybe life is so difficult to create, that Earth is the only place it exists.
