I WANT TO KNOW IF SOMEBODY IS LOOKING AT MY FACEBOOK PROFILE WITHOUT MY KNOWLEDGE

You can't, otherwise every time anyone went to anyone else's page, it would tell that person. If you don't want someone looking at your facebook profile, then you shouldn't have made a profile. You could block them or change the permissions on your posts, but all they have to do is create another account and send you a friend request that you accept. An alternate solution would be to delete your page, but the content is still on the internet ( or their hard drive ). A third option, if there is little to no risk of harm, is to let them peep if they already are.

no, it is not possible

You cant, because Facebook wont provide you such option.

Your question is so foolish

"I WANT TO KNOW IF SOMEBODY IS LOOKING AT MY FACEBOOK PROFILE WITHOUT MY KNOWLEDGE"

Every body can see every body profile without there knowledge, as well as your friends and also you can see your friend profile without there knowledge .
