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...
