Have experiences and respect other life. That's really it.
The Earth created lifeforms that can understand the universe. Even if there are other conditions out there that can create life like that, it's not common. There is unfathomable empty space between planets and their moons. To say nothing of between planets or stars or galaxies.
Good news! You're one of these rare combinations of matter that can understand the universe. In a real way, we are the universe trying to understand itself. Scientists explore it in a deep way, and should be respected for that, but you don't need a PhD to participate. A single celled organism who figured out better ways to swim in its little pool helped the universe understand itself. The first human to taste a strawberry helped the universe understand itself. Have experiences.
There's a lot of other life also participating in this, and they should be respected, too.
