I'm not sure I understand exactly what youre getting at.
Are you stating that all skeptics and debunkers dont believe in alien life. I'm a skeptic and I believe in the existence of aliens. I'm waiting
for the 'Holy Grail' of evidence. But what that evidence is, depends on the views of the skeptic. For me, it would be meeting an alien. On that
day my belief will change to knowing. Same as you don't believe in shoes. They're there, on your feet. You don't need to
believe in the
shoe for that.
The 4.6 billion year thing is also a bit puzzling to me as well. Life is theorised to have originated on Earth between 3.5-4 billion years ago.
Out of that time, humans, as we know them, only originates about 60,000 years ago. 60,000 compared to 4,000,000,000 years is hell of a difference.
A higher intelligence
could have originated earlier if the factors were right (some believe they did, but thats another story), OR never at
all. It's all probable. If we're wiped out like the dinosaurs, will something as/more intelligent evolve?
Drakes Equation takes these factors and more, into consideration. Even that is under a
rethink
Then you come to lights in the sky. I don't get excited about fuzzy blobs of light on video, as all I see is a fuzzy blob of light. We're still
discovering things about our planet. What we perceive as a UFO today could be a rare natural phenomenon that requires investigation, or it could be a
ship from another world/dimension.
