Best photography camera for beginners?

Im looking for something under $500

Here are the things I plan to take pictures of:
Nature
Scenery
Concerts
People
Animals
The sky

Just very basic things but I want it to be very high quality. I want to be able to play around and make things artsy like blur the background and stuff. I just want really high quality pictures. It would be cool to be able to see starts in the pictures as well like the night sky with the moon.

I plan to use it for a hobby, nothing professional or anything. Thanks!
