In space there are millions of millions of light years of room. Humankind can’t even get out of the solar system. The sun is a tiny thing compared to space and even this is bigger than 1,300,000 earths. So if the sun is peanuts next to space then what are we? Could we ever do anything that could possibly make a difference? If we were to blow up the planet what would that do? One meaningless planet in one meaningless solar system would be gone.
