Johan:

1. How it all began?
Don't know. Neither do you. Neither does anyone. Every current answer whether scientific, relgious, philosophical, or other is not correct. What science can tell us is precisely where it all was an actosecond after that point-in-time.

Now are you going to conclude that because no one knows the answer you must create a mythical creature and bestow upon it supernatural powers?

2. Purpose of life?
For me? For you? For amoeba? For zebra? Or would you like me to offer up an answer that applies to all life-forms in all galaxies in all possible universes?

For me? It is turning oxygen into carbon dioxide. The longer I can continue doing that the better.
