There are three supreme laws of nature - creation, preservation and destruction, that cannot be denied. We see it all around us. You can call them the holy trinity or the three supreme gods - Bhrama, Vishnu and Shiva. Our Universe was born through a violent destruction cycle which means destruction gave birth to creation, and that means Shiva or the destruction energy is the supreme lord of the Universe. Not to be taken literally, as in a human shaped dude.
Everything will be destroyed eventually and will be born again through a new cycle of destructive energy. Humans are pretty irrelevant, we should just be grateful to be born on Earth but we tend to fuck everything up. The mere fact that humans talk about god is hilarious in the context of the size of the universe. Stay in your lane.
