Mankind Will Live On Other Planets Someday
The notion of inter-space exploration and extension of humanity to the stars has been around since the days of famed sci-fi writer H.G. Wells. It all makes for good movies and books, but doesn't have any biblical support. The reason is because of what God told Adam & Eve:
God blessed them said to them, Be fruitful and multiply and fill the earth and subdue it, (emphasis mine) and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.” (Genesis 1:28)
God didn't tell them to subdue the galaxy or the whole of creation. There's no authority for us to subdue and dominate any alien creatures. Folks will respond with something like, “God says in Genesis nothing that humanity proposes to do will be impossible.” (Gen 11:6) However, you have to qualify such statements with the rest of scripture, not just rip it out of context and conjure up I-think-so's. The clear command is to multiply, fill the earth, and subdue it and the creatures that inhabit it. Period. To claim that someday mankind will multiply, fill the galaxy, and dominate it is not part of God's plan.
God made one race, the human race. There are no alien worlds out there, plotting to send faster-than-light (FTL) battleships to earth in order to dominate, rule, make us better, etc. If so, Christ would have had to be born on other planets and do the whole die-on-a-cross nightmare over and over again.1
Perhaps the biggest factor against space exploration is lack of sustainability. To date, no one has found a planet with water on it. Oh, yes, I've read about the “ice cap” on Mars and the potential for ice on asteroids. But they really don't know. Most of it is speculation. Besides, the current goal of colonizing Mars is fraught with danger. No breathable atmosphere, no ores, not a lick of wood, stone, or other usable resource. Everything would have to be brought from earth, a two year wait for the FedEx guy to deliver.
There has also been zero discovery of any inhabitable planet, based on spectroscopic analysis of everything out there. And even if there were, how would we get there? The notion of reaching light speed was pooh-poohed by Einstein decades ago—it's not possible. Google it to find out more. Worm holes and folding space are all theory, based on science fiction, not fact.
In his book, The Devil's Delusion, David Berlinski (an atheist physicist) studied the mathematics used by his peers to “prove” their theories on multiple universes and other astronomic ideas. He found that most of it was absolute nonsense. They never figured on someone like Berlinski—one of their own—to expose their bogus formulae.
My friend, you will be long dead before humanity strikes out for the stars. Why don't you trust God's Word for what it says and get yourself right with Jesus. Once you've gotten eternal life and you're living with God, you can them ponder the distant galaxies, if they still exist.
1Some may disagree, asserting that just because humanity sinned it doesn't mean races on other planets did also. Simple mathematics proves otherwise, however. Someone is going to reach for the forbidden fruit. If Adam & Eve hadn't done it, one of their progeny would have.
