ALIENS TAKE Human slaves ??

ok I admit it I think Aliens are around  us  ,here on planet earth , I just had this thought  say if the aliens were a million years a head of us  or even more o and  say there were hundreds of these planets
and they know all about  us and they say to each  other Hey check out the blue marble planet  they have a new civillastion going  on   Like a young child or something good to eat   they look at  us     I am sure lots of people have gone done this path of thinking        The question is are we at the stage where we can understand / comprehend them

and Im just thinking why spend all this money trying to get to mars to look  for a load of BS
WHEN  THE ALIENS ARE HERE 
ITS TIME  for  WORLD GOVERNMENT    UFO  CONFERENCE
NASA  should be investigating the alien question      IN FULL PUBLIC VIEW
They should have a very public attempt to answer  the question
I see lots  of  stange objects  in NASA  videos and all the other evidence
I have been a 99.9 beliver for about a year now  There are 2 many  good people  saying  they have seen alien ships  There  seems to be lots of diferent shape vessels,seeming to mean different aliens , I think some  people would like to know the truth and
 other   very  powerful   people would   not like the truth
Why cant a lot smarter people than me  see the need for a world comference

Could  the aliens be taking  human slaves  from our planet  in small numbers or worse something they are doing to us we cant even imagine !!!!  What if aliens think humans are pretty tasty andd ever now and then  they go on hunting trips for some nice fresh earthlings Some aliens prefering  white human  meat  others may be  like dark human  meat  or whales or Lions  or Lobster  even

There is too much  evidence to ignore any more
