Pay close attention here lsufos. There is an outside chance you could learn something.
First, I presume you did not mean what you typed above, but meant this:
You would have to be a right dimwit to believe that there is no life on other planets.
No. You wouldn't. There is almost no evidence for life on other planets. The single exceptions are two controversial, and generally discounted, instances relating to Mars. [See below for a fuller discussion.]
There are several well considered reasons to
suspect that life may exist elsewhere. These are different from evidence. Attempts have been made to estimate the probability of intelligent life existing elsewhere in the Universe, or in our Galaxy. These estimates are often expressed in terms of the Drake Equation.
A reasoned discussion of these probabilities by Ward and Brownlee in their book
Rare Earth concludes that while primitive microbial life may be commonplace, complex lifeforms will be rare, and intelligent life may even be unique.
So, you would not be a dimwit to doubt the existence of life on other worlds, merely sceptical in the absence of any objective data to support that contention.
Issue 2:
Even MARS......Now that is near but they Scientists will be wrong in your eyes though.
As noted above Mars has provided the only evidence for life on other planets:
a) The nanobacteria allegedly present in the meteorite ALH84001.
b) The disputed positive responses to the Viking experiments on the surface of Mars in the 1970s.
Both are rejected by the scientific community at large. I go along with the rejection of the ALH84001 bacteria: far too tenuous an interpretation. On the other hand, I strongly suspect that the Viking tests
did reveal dormant microbial life forms in the Martian soil. Future Mars exploration will reveal the truth.
What does this say about the possibility of widespread life on planets in other systems? Unfortunately, almost nothing. The planets of the solar system routinely exchange material as a result of impact. Life could have originated on Earth or Mars and travelled to the other inside ejecta.
Issue 3:
Life versus intelligent life versus intelligent life visiting this planet versus intelligent life visiting this planet today
I am fairly certain that life is widespread throughout the Universe. That does not mean intelligent aliens are visiting the Earth today.
I consider it possible, even probable, that intelligent life may be found elsewhere in the Universe. That does not mean intelligent aliens are visiting the Earth today.
I consider it possible, though of questionable probability, that intelligent life forms have visited our solar system in person or with robotic craft in the past. That does not mean intelligent aliens are visiting the Earth today.
To assess the likelihood of any and all of these possibilities requires an objective assessment of the evidence. You, lsufos, seem incapable of that.
Issue 4:
Intelligent life, LIKE YOU SPOOKS HERE WOULD NOT GO LOOKING YOU GOT TO HAVE BELIEF IN IT.
Sonny, I suspect I had an interest in ET before you even existed. [If I have underestimated your age I have also seriously overestimated your intelligence.]
Do you even know about Project Ozma (without running to do a quick google?)
You say I would not go looking for ET:
I fully support the various SETI projects currently underway.
I applaud the plans to build telescopes large enough to resolve continents on extra-solar terrestrial sized planets, and to detect atmospheric composition.
I favour investigation of our solar system for evidence of robotic observation devices left or sent by alien intelligences.
None of the above require that I believe in alien intelligences, only that I acknowledge their possibility and their importance.
And none of this has any relationship to purported alien spacecraft. Has it occured to you that the scientists who are engaged in the various SETI programs, and research into life on Mars, or any aspect of exobiology, all of them are quite dismissive of the UFO phenomena.
If you seriously have an interest in alien worlds and alien life then stop jamming up the airwaves with UFO
noise. It distracts from the serious business of proper research.
