Thomas Zurbuchen, the associate administrator for NASA’s Science Mission Directorate, has revealed that it is very likely that life beyond Earth exists.
“Is there life beyond Earth? I think the answer is yes — but we just don’t know,” Zurbuchen said during an interview at Boston University.
“The simple reason I think so is because we underestimated nature when we doubted whether water or complex molecules would exist beyond Earth. Each one of those is much easier to achieve than we thought possible.”
And putting all conspiracy theories aside, when you think about the possibility of life having developed elsewhere, it’s common logic. It makes more sense to believe that in the vastness of the cosmos, life developed somewhere else too, and not just on Earth.
Why? because space is so incomprehensibly vast that somewhere out there, the right conditions for life must exist. In fact, we have already discovered planets that may harbor the necessary conditions for life ( as we know it ) to exist.
In addition to that, we recently published an article where Harvard scientists suggest that of all exoplanets that have been discovered in the universe, most of them are probably water worlds.
And where there is water, there is life.
Not necessarily though.
As noted by some experts, the fact remains that earthlike conditions in outer space do not spell out life, and University College London biochemist Nick Lane has argued argues we don’t have any sort of statistical justification for that assumption — arguments like Zurbuchen’s are extrapolations from the singular data point of life on Earth, reports Futurism.
But whether Zurbuchen’s is right or wrong, the associate administrator for NASA’s Science Mission Directorate believes that finding alien life won’t make a bit of difference if we don’t first make sure that Earth can continue to exist and harbor life in the future.
“No matter what the answer to that question is,” Zurbechen replied to a question about off-world settlements,
“we have to keep Earth livable. It’s unsafe to do otherwise. I do think about terraforming other planets a small percentage of the time, but much more time I spend focused on ways to keep the Earth livable and wonderful — not the other way around.”
If we don’t address the ongoing damages that are being caused by global climate change, Zurbuchen seems to be implying, any space-exploring extraterrestrials won’t find anything more than the remains of our society, fragments of our glorious civilization, that once existed on Earth, and brought upon itself destruction, without having ventured out into outer space.
