Aliens, They really exist or not ???

I don't know whether there is any living things other than earth, Yea I watched lot of videos on YouTube, read such stories like Alien Abduction, Alien caught on tape, etc.. Personally I neva seen a Alien before, But still there were no such Real records or exactly HD videos available there or not ... Users were uploading videos daily ... But still no one no...

Yea, So how can we know that they really exist or not ? If aliens exist then somehow they found us .. They may b our friend or enemy, I am not sure... But If we out such things in A order A god, Satan, Angels , Demons, Sprits, Jesus, Allah, etc and then new thing come among us that is Alien ... Isn't it something like odd.. You will say Naahhh, these things are different... Just like we neva see god , yea personally I neva meet him but yea I can feel his/her presence.. By bad things you can feel devils... By spirits you can feel ghosts, sameway By stories, discussion, videos, you can feel that yea, may b alien exist ...yea ... Why not ... They could be... Just like us ... Not only one but others too.... But at very large distance *about light years* and exactly we doesn't know their locations too...

May be they neva exist , those videos are fakes, some type of natural phenomenon or a pranks, just a hoax ... We are not sure not even you !!! We see a lot Ancient Aliens episodes, after watching them seriously everyone come to a point that yea, how could be praymid build in soo less time, those Mayan civilizations, Etc... But all those were history, and we don't know what happened at that time ... No ones knows what's happened , who come, who goes?? Aliens man's gods spirits, no we can't trace those things by a structures, by videos, we have to be particular to such things ...

For example, to know about moon we send a rocket, to know about earth we send a satellite... To know about ocean we dive deep in seas, To go one place to another place we create a mean of transportation like bus cars airplanes cycle etc... So why we couldn't do in these cases ... But we just made a system called something like SETI, satellite... But still doesn't know the answer because we are not sure ... No one can tell our answers rather than TIME, yea Time would tell us everything...

Its About

Sacrifice

Its a most toughest work to do in this world, if you had kind heart then only you can do, there is welfare for us but others there it is, after do sacrifice there is nothing remains for us, not even try to regain something for yourself from sacrifice, If you want to do sacrifice then obviously you should have enough courage and will power. Enough strong to resist the pain. 

          You know what? After doing sacrifices may be people know your sacrifice otherwise they didn't care. Its not about loosing or gaining its about someone happiness, its very difficult to loose your loved once, If you really love them you should. Life always carried out from sacrifices, you mother sacrifices when you were born,even now she is sacrificing. True lovers sacrifice, yea I am one of them. For her happiness I sacrificed, Its very difficult but somehow I am doing because I do true love. It doesn't mean I ended my love, Its just about my feelings.
          Even nowadays no one want to sacrifice only good peoples remains there who are doing sacrifice for their family,loved ones,relatives, some people often sacrifice for strangers. It not like a work, its like you are cutting one hand with the help of another hand, yea I am talking about hand because after loosing your hand still you can survive. 

SO, IF YOU EVER GET CHANCE TO SACRIFICE, WOULD YOU?
