Of course yes my friend. We are not alone
But also exists the DRAKE EQUATION
The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy.
Look at Google about that equation and explode your curiosity =)

Well of course we cant be the only living things in this whole galaxy and plus there are other galaxy's as well there's life bound to be there and dont forget about area 51 thats some freaky stuff like we know the government hides stuff were not that stupid we know that UFO's and aliens exist i mean hello here we cant be the only things alive in this whole solar system and if you read up on stuff way before Christ and after you know the pyramids right no humans could have just done that :/ well thats my opinion anyways but seriously and the things they would carve in stone like the little pictures some of them be looking extra weird at times
