Maybe but searching for meaning in all this is pointless. I am here. That’s enough for me. I won the universal lottery and got to exist.
Justifying a reason doesn’t make sense to me. Rocks don’t have a purpose they just are. Flowers, while they do things do not do them to have purpose they just do. The doing gives them purpose.
So do and you will have purpose. Create and grow and that is “enough” if you need to put a flag somewhere.
