Ah, that's just your DNA talking. Otherwise we could be immensely pleased with the amazing experience of being alive, and when our time is up allow Mother Universe to move on without us. Perhaps after we are wiped out, another better form of life will take hold and really do amazing things, fueled by our decay.
Besides, it looks like our own behavior is going to do it for us, so might as well "love the bomb".
We are alive as far as we want to be alive. We can be that "better form" of life, it's questionable that a better form of life can emerge from scratch. If our own behavior is going to get us extinct, so be it, let's help the nature then!
Besides that, I think that personification of "Mother Universe" is just a xenophobic form of human fear of the "otherness" surrounding us. There is no monolithic Mother Universe, more probably, there is a mesh of living creatures and natural phenomena we are a part of.
I guess that speaks to the dichotomy of urge in humans. We are equally as likely to sit on our butts staring mindlessly at something on a screen as we are to strive for extending the reaches and hopes of our species.
I hope it could be us that will do those amazing things you mentioned.
