Why? Why do things exist? Plants, animals, people, planets, stars… everything. Why do they exist? I do not think physics or science can answer this question. Science may be able to explain how things work and what causes what. But the Why questions, I am not sure Science can ever answer. But the various religions have a similar shortcoming. They say – if you do this you go to heaven or if you do something else you go to hell? Or they say if you do this you will be happy and if you do something else you will be unhappy. But I have not seen a decent explanation as to why everything was created. Just to see if we the creations behave properly? That’s like saying we have kids so that we can give them treats/punishments based on whether the kids behave well/bad.
