Although I'm not a scientist, it doesn't take one to understand that by numbers alone, the possibility for alien life outside our galaxy or even in our own galaxy, life most likely exists, and the sightings we all hear about can very well be the reason. Okay, we know that our own galaxy is not the largest, nor the smallest, but yet it would take thousands if not millions of light years to cross from one end to the other.

Those galaxies outside our own would take billions of light years for a craft traveling at the speed of light to reach us, and for that reason, we would have to assume it would be a impossibility for the most advanced civilization to live long enough to travel such vast distances for that amount of time. We are on the threshold of understanding how worm holes could be utilized to travel from one end of the universe to the other without the time necessary to do so using them as a "shortcut" through time and space.

For those who are in the dark as to how many miles light travels in one year at 186,000 miles per second, not miles, but every second, we have to multiply 186,000 x 60 (for one minute) then multiply that number again by 60 to represent the distance for one hour of travel, then multiply that number by 24 hours, then multiply that number by 365 days, and you should have a number so long it just would be too large a number to use for determining distances such as we have in our universe.

So that is why we use the term "light year" for posting the distances between the stars and us on this planet. Each light year represents that huge number of miles from the math I just used. So we can totally understand how the use of ordinary measurement would be almost impossible to use because of how huge the numbers would be. That said, we can only dream of the day we would be able to attain light speed, and if we did, so what?

Just to reach the closest star would be far too long of a journey for us to be confined in a craft for the amount of time to reach it, and that is not to mention that we would need a craft that can produce it's own gravity as we know it takes several months for astronauts to regain what they lose in bone mass and muscle tissue from being in space for any lengthy period of time.

So if what we see, or imagine that what we see are UFO's, then where could they have come from? One strong possibility, which is a theory of my very own, is that they just may be from our very distant past. We know that traveling at the speed of light, time
