I know this is for Skip, but I'll reply also.
1)Conspiracy, what conspiracy? A quick search will provide many expert witnesses such as Gordon Cooper, (Already discussed) Redenlsham witnesses,
Shag Harbor, just to name a few.
As far as why some would like to keep this quiet, I suggest you do a search for a study done by Nasa that recommened any knowledge of a
extraterrestrial presence should be kept under tight wraps, for many reasons. I believe this study was done during the 40s or 50s during several UFO
flaps. Fascinating
What is the aim of the aliens? Ask them. Speculating here, but I would think just to observe and study, just as we do with lower life forms.
2) What form? Most abductees say the aliens are greyish/blue with large black eyes, skinny bodies, some short some tall, with long arms. That
description is probably similar to what they look like, as it has been reported on every continent on the planet.

P.S these reports have been
coming in before the inception a planetary communication device such as the internet.
3) They come in space vehicles similar to a Nasa space shuttle, but obiviously much more advanced. Hope that helps in your journey Paul. Good
luck.
