Well I was going to address these answers until I got to your suggestion to buy a book on lateral thinking. Maybe instead of me buying a book
on lateral thinking maybe you should by a book on deductive reasoning.
Hehe, I have that one as well. The Logic book, 4th edition, by Bergman and Nelson. A standard text at universities for logic.
There is a problem with your argument, it goes something like this:
1. Aliens have technology to travel billions of light years
2. But their UFO's sometimes crash
3. Therefore aliens cannot travel billions of light years.
The conclusion does not follow the premises, so the argument is invalid. There is no premise here that says, "Aliens that have technology to travels
billions of light years cannot crash" and if you state such a premise you have to first prove the premise is sound. As a matter of fact it isn't,
just because somebody has the technology to do light speed travel, it does not follow they have a zero attrition rate. Moreover, you do not have have
the statistical data on UFO sorties to know whether they have a good or bad record. They maybe flying billions of sorties, and only have an attrition
rate of 1 in every billion sorties.
Your other argument that these UFO's cannot be shot down is just as invalid. To state: Just because aliens can travel billions of light years does
not mean that they are invincible.
Anyone can make up a bunch of answers. Half of the ones you gave dont even make sense.
They are not answers, but possibilities. You are arguing for an unknown, you say "Why would they be interested in us", but how can you know that
they would not be interested in us? So my possibilities are just as valid as yours, but, far more likely. They are more likely because we too abduct
other species, run tests on them, experiment with their DNA, collect them as resources. So why can't an ET species do the same to us?
You really do need that lateral thinking book
Edt: Here is another lateral thinking exercise: Why is it billions of light years? Why not
1. Millions of light years
2. Thousands of light years
3. Hundreds of light years
4. Tens of light years
5. Under ten light years
