Here is an easier way of saying it: Number of UFO sightings proven as natural, manmade phenomena, or hoaxes: many
Number of UFO sightings proven as alien crafts: zero
Therefore, just like whales that live on land, we can inductively reason that aliens have not visited this planet.
Do you believe out of all the sighting ever, that it's possible that any of them could have been alien in nature?
No, I don't believe its possible.
Do you personally believe life in whatever form exists outside of this particular planet?
I don't know. That is something that it inherently unknowable at this stage in human history. I am open to the possibility that in several hundred years we may be able to drill into the glacier seas of Europa and find undersea life. But there is no evidence either way at this point.
As for outside the solar system, I do not believe that faster than light travel is possible. Therefore, we will never know.
When the Sun dies in several billion years, we will most likely have colonized other planets. However, mankind will die never knowing whether there is extraterrestrial life outside of our solar system.
Not according to Jesse Marcel.

More seriously, who might those crop artists be? And what kinds of advanced technology might they possess? Experienced researchers continue to hold many different opinions concerning such matters. Most of those opinions should be respected. After all, if crop-circle research has not taught us tolerance and respect, what have we learned? But for simplicity, I have summarized my own personal views below:

How can these amazing things be possible?
1. No ordinary human, living on Earth two years ago, could have predicted that Comet Holmes would soon explode at a precise location in the constellation Perseus.
2. No ordinary human, living on Earth two years ago, could have predicted that Comet Holmes would soon become so bright, that its conjunction with Mirfak on November 21, 2007 would become a notable event. . . .
By sending us many detailed pictures of the outburst of Comet Holmes, over two years before it happened, those crop artists have clearly demonstrated that they can predict certain aspects of our modern future here on Earth: and that may be the most important point. Indeed, we have only five years left now until an end to the Olmec-Mayan Long Count calendar in 2012 (on a winter solstice). What might happen then, if anything?
Another crop picture from Crabwood 2002 told us in plain English: “Much pain but still time”.

I find this interesting . . . and assertive of an other worldly hypothesis.
In addition to those who’ve been around such craft personally and assert that they are other worldly.
Yet on the other hand, you and at least one other here has stated that many or some of these sightings could be top secret government black ops craft, etc. Since you have alleged that many of these sighting could be government secret craft, do you feel it possible the government might have some evidence of their existence?
Do you believe out of all the sighting ever, that it's possible that any of them could have been alien in nature?
No, I don't believe its possible.
OK.
Do you personally believe life in whatever form exists outside of this particular planet?
I don't know. That is something that it inherently unknowable at this stage in human history. I am open to the possibility that in several hundred years we may be able to drill into the glacier seas of Europa and find undersea life. But there is no evidence either way at this point.
OK.
As for outside the solar system, I do not believe that faster than light travel is possible. Therefore, we will never know.
Do you believe in the big bang scenario? It is believed that the initial expansion exceeded the speed of light. However, I personally don't believe rocket powered craft will ever cut it for reasonable interstellar travel. There might be another way to travel between the stars though.
When the Sun dies in several billion years, we will most likely have colonized other planets. However, mankind will die never knowing whether there is extraterrestrial life outside of our solar system.
What if micro-organisms, or evidence of past life are found say 5 feet beneath the Martian surface in 20 years or so? Would you believe it if told?
Do you believe it's possible, that life, micro-organisms etc, could have been scattered, or carried off into space by extreme large impacts during earths ancient past?
To be clear here, I personally believe their is other life, in one form or another in the universe, outside earth. As a matter of fact, I think it would be more mind bending if earth were the only rock in the universe with life on it. JMO.
