The Universe is unimaginably vast. It does not have purpose. It simply is. In the face of the Universe’s near-infinite indifference, we must decide our own purpose.
We might decide that our actions are inconsequential, but that isn’t true. Everything has meaning, if we decide that it does.
We might decide that nothing really matters. If that’s true, then why not choose to do something nice? If malice doesn’t matter, then what purpose can it serve?
The Universe does not care about you. But people can, will, and do.
The Universe contains not only all of space, but also all of time. What we perceive as the past still exists. It always will exist. Like the Sun above the clouds, it stays there even though we can’t see it. It will always be part of the Universe. All the tiny things which make up who you are will always be who you are.
That one time when you did something nice for a complete stranger for no reason? That will always be who you are.
A very good book on that subject https://www.thebeginningofinfinity.com/
