Beyond the limits we know

Maybe I am skeptical. It it strange and difficult to understand that if there were any kind of intelligent creatures beyond our limits why nobody has come closer enough to make us know about them. Why all the information we have is so mysterious and full of contradictions? Maybe the idea is that we will never know each other because that is the will of the master of the universe called God or any other name that you want to give to Him. We are living perhaps different degrees of difficulties in different states so as to achieve perfection. I do believe that the earth is the material world and there are many other spiritual worlds waiting for us out there in the space.
