If there is life on other planets, they will have to bow to the Lordship of Jesus Christ. Refer Phil 2:10-11.

We can say with mathematical certainty that there is not Human Life, in physical form like us, on another planet. There are 10 to the 82nd power atoms in the known, observable universe. There are over 260 physics variables making human life possible on earth: force of gravity, size of planet, presence of moon, location in the solar system, size and location of Jupiter, distance from the Sun, size of the Sun, type of star the sun is, placement in the milky way, composition of the core of the earth, and etc.,.etc.... all necessary for life as we know it. So the chances that there is "someone like us" out there are less than 1/3 of 1 out of every atom in the known universe.
Scientifically, we are special; though we live on a planet it is much better understood and described mathematically a life raft of sorts, a capsule or an escape pod traveling through space on a preplanned trajectory.
