Does the existence of the universe have a purpose, or have meaning? Why do we have sentience? Is our purpose just to eat, reproduce, and die? Should we express gratitude for our existence and ability to comprehend the wonder of the universe? How should we direct our expression of this gratitude? These are basic philosophical questions that are not answered by science. Can you answer?
My belief is even in science Stephen Hawking said before the big bang singularity there was nothing - there was nothing in this universe only darkness and God wanted to bring light and matter into that darkness.
God has sentience - part of his essence is in the living beings of his creations.
My personal belief we are here for judgment. Being placed here on Earth, made of the things of Earth, nourishment is necessary. For all spirits to be born in the flesh in a continuous uninterrupted fashion reproduction is necessary and to prevent overcrowding earthly death of the flesh is necessary -
Expressing gratitude is an individual choice and how or to whom the gratitude is expressed. One believes in God and express gratitude to him or one don't.
From the scientific point of view it was all a big accident.
