Longterm survival of mankind

Hi all. Im new to reddit, and wanted to ask this community a question that might be really hard to answer :). I'll try anyway.

I want to adress a couple of things regarding to the longterm sustainability of mankind together with our environment on earth as we know it. Id like to take two paths and talk about both of them, both relate to longterm survival of not only mankind but also civilisations in general across the universe. 1. Right now, we are coming to a point in time where technology will reach a certain point where the fundamentals of our society will be built upon 100% renewability, so we can, in theory, live on this planet with all the needs that we have as long as we need to. Getting to this point is obviously not a matter of if but more of when. One day, we'll have to, to survive, and to let our earth survive too. Elon musk has set goals to enable such things to happen. He wants us to create a civilisation that will harness all its energy from resources that will last for 'eternity' or at least tens of thousands of years, without harming the environment. This is where my second thought comes into play. 2. How likely are we to succeed this longterm survival goal of ours? As almost everyone knows, doomsdays are not just hollywood blockbusters. They are in fact reality, and may sooner or later strike the earth, wrecking all of mankind and other species, sending us back into the stoneage, IF we even survive as a species. A lot of these things might even happen today. Yellowstone should erupt every 700,000 years or so. We're currently at 700,000. Soms scientists even claim that we might see it erupt within 80 years. We'd most likely not survive as a species, and as i stated, even IF we were able to survive such scenario, we'd be sent back into the stoneage, a new ice age, and probably less then 1% of humanity left. This is just one of many doomsday scenarios that could wipe us out. Since these things are naturally caused by the fact that this is how the universe works, by changes, waiting to happen when time progresses in a ever expanding, limitless universe, what if this actually is one of the reasons for the fermi paradox, and one of the theories stated as; 'the great filter theory'. What if civilisations have had many chances to become a space faring, 100% sustainable civilisation, but there were just too many filters that caused them to be wiped out of existence. If that is the case, our destiny is around a 100% likely to be the same, it will just be a matter of time. This really gives a chilling thought. The universe knows no rules, no humane laws that save planets and its inhabitants. It completely takes out the idea of a caring upper being like 'god' who makes sure earth will be allright. Coming to the point, what im worried about the most is that mankind progressed at the wrong time, and will never be sustainable untill we reach the far corners of our milky way, because stuff like super volcanos are, right now overdue. What if it was never meant for any intelligent species to develop itself into something as big as a space faring civilisation. Im sure there have been many who were at our level or further who were wiped out by some event that destroyed all life, it might really be about having the most luck. My question is, how likely are we to achieve this kind of civilisation without being wiped out in the progress, and im talking about long longterm. Not a thousand years, im talking at least tens of thousands of years.
