There's nothing for humans to do in "other places to live" either. We accomplish nothing by being here. In fact it would be better if we gave up already.

A human is born in need of air, water, food, and pastime, and the best we can do is satisfy these needs only partially. There is no reason to create these needs (other than to partially satisfy existing needs that didn't need to be created), but there are many reasons not to create these needs.

You correctly note that the universe is extraordinarily harsh. I see no rational reason to continue fighting it. There are only superstitious reasons, like pride, sunk costs, think of the children, equivocating humanity the race with human the individual, identifying with your genetic material, assigning intrinsic value to life, etc.
