Dr Gentry Lee, who worked on the Mars Viking mission, has spent decades designing probes that land on other worlds.
Speaking recently at the American Association for the Advancement of Science (AAAS) conference in Phoenix, Dr. Lee expressed his opinion that alien life is still out there for us to find.
"[It has] just got to be there somewhere," he said.
"We are going to find life of some kind somewhere else. The odds are overwhelming."
That said, he didn't think that intelligent aliens had ever visited the Earth.
"There exists nothing today that says any alien or any alien machine has ever landed on the planet Earth," he said. "If you believe otherwise, you are being misled."
On the subject of finding life on other worlds, Dr. Lee stated that scientists would need to be ready to find forms of extraterrestrial life that are very different to anything we see here on our own world.
The Earth, he argues, may actually not be all that interesting to an alien scientist.
"Extraterrestrial biologists would come to the Earth and would go back and report: 'Not a terribly interesting planet. All life is the same.'"
"'All of it reproduces in the same way using the same major [DNA] molecule.'"

I stay firm on one glaring fact, aliens would face the same daunting task we would to travel the vastness of space, that's assuming a being capable or interested in space travel is even existing out there, look at our planets creatures some are pretty darn intelligent but we are the only earth creature trying to go into space.
That would be very presumptive. As you might have noticed from UM, or life generally, confidence is very often (and increasingly) positively correlated with being mistaken, e.g., as demonstrated by certain political leaders whom you may be…obsessively…decrying on a daily basis. Rather, making sweeping generalizations and statements may make someone feel authoritative, and people who themselves want to feel authoritative and validated subscribe to that behavior. I’ll go out on a limb and propose that we meat bags crawling around the surface of this planet, occasionally sitting on a co... [More]
And admit that we don’t know everything? Many people around here, such as the one quoting you are way too invested in their own beliefs to allow that admission. In any event, it’s fine to hear people claim that there is extraterrestrial life somewhere in the universe, considering how ridiculously large the universe is, that makes sense. But, it’s really not saying much is it? In any event, I’m always interested in the testimonies of people who are sometimes on their death beds, or in old age, who have worked on secret programs for the government and claim that they had first ...

There is a certain insecurity with the acknowledgment and understanding that, for example, we don't know everything, are not completely in control of our lives, can be victimized by circumstance, etc. Different people deal with that insecurity differently. The default position with respect to UFOs, Bigfoot, etc. or almost any topic is one of indifference: "who cares, really?" Well past that, you have self-righteousness, and then severe antagonism toward not only ideas, but the people entertaining them. Expressing that antagonism perhaps assuages that insecurity for some people, and the... [More]
13, his point was simply that he obviously wasn't being scientifically balanced, because statistically......... you know the rest...... the Universe is so vast, that simply our neighboring galaxy could easily contain hundreds of planets with formative(early, microbial or even evolutionarily advanced life) just like we obviously did on this planet. This is not imagination, this is not fantasy. This is not science fiction, this is a mathematical and evolutionary fact of nature. Unless you believe that humans are so friggin' unique that we just popped out of friggin' nothing, and only us alone. H... [More]
You are confusing probability with proof. No serious person argues that humans "popped out of nothing." Evolution explains how life diversified once it exists. That says nothing about how often life begins in the first place. We currently have exactly one confirmed data point for life in the universe... Earth. From one data point, you cannot extract a "mathematical and evolutionary fact of nature" about how common life is elsewhere. You can form hypotheses. You can build models and you can argue it is plausible. But you cannot promote that to a proven inevitability. Bottom line... Speculating ... [More]
That's true. Bur it's not like we haven't been looking for decades now. Every so many years more and more powerful scopes and sensors deployed and still nothing detected that could be verified.
