In response to the statement that other animals die and yet they have no sin. Yes, this is true, but it states clearly that man is made in the image of God and it does not state this of any other creature that was created on earth. No where are the animals given eternal life in the book of genesis. It simply states that the penalty for Adam and Eve for eating of the fruit of the tree of knowledge would be death. As well, God states that Adam and Eve were told to leave the Garden of Eden so that they would not eat from the tree of life. So, in the end, neither the animals, nor Adam and Eve, end up with eternal life, just as things are with all life on earth today.
As for aliens in the universe, you must read things carefully in the Bible. I for one believe not only that there are aliens in the universe, but that God has told us about them in so many words of the Bible. For instance, in the book of Genesis God speaks of the Nephilim in Chapter six. It says, “When men began to multiply on earth and daughters were born to them, the sons of heaven saw how beautiful the daughters of man were, and so they took for their wives as many of them as they chose.”
Now read this very carefully and you will notice that it mentions the sons of heaven as a different race of beings that are separate from man. How can I think this? It is because it mentions man in general referring to the entire race of all men. In other parts of the Bible men are instead called by where they come from, for instance, the Philistines, the Israelites, the Canaanites, and the Hittites and so on. Yet also notice that the Sons of Heaven are called by where they are thought to come from and by whom. They are from heaven, yet they are called sons, in obvious reference to physical beings as Christ is called the Son of God. They would have to be physical beings in order to take wives from the daughters of man. If the Sons of Heaven came from the earth then they would be given a name by where they originated from even if it were as vague as saying they are from the east, as the Bible mentions that the Magi who followed the star were from the east.
A little while later, the book of Genesis has this to say, “At that time the Nephilim appeared on earth (as well as later*), after the sons of heaven had intercourse with the daughters of man, who bore them sons. They were the heroes of old, the men of renown.”
Notice that the Nephilim are mentioned as separate from the sons of heaven. As well, they are listed as separate from man also. But notice most importantly that it is said that they “appeared” on earth. How did they appear? As well, what is very important is the wording “(As well as later*)”. What is important about this is that the book of Genesis begins talking about the great flood as soon as this passage ends. The great flood destroyed all life on earth. So, how can the Nephilim “appear” on earth later than the great flood unless they had the ability to leave the planet and then later (after the flood) return to it? The name Nephilim also is a clue for one of the oldest possible definitions of the word Nephilim is the Babylonian meaning of “people from Orion”. Nephila is another word for Orion and of course Nephilim is the name given to the people from this place. It is extremely common for people to be called where they are from in the Bible, as we have all ready discussed. So, not only does the Bible mention one separate physical entity from man, but two, the Nephilim and the Sons of Heaven.
Add to this the fact that our own modern knowledge of God’s universe has it teeming with galaxies full of stars. Did God ever say that we were the only ones that he created that were made in his image? No, instead he mentions in Genesis chapter 3 verse 22, “See! The man has become like one of us, knowing what is good and what is bad!” God says the word us very clearly so that it must mean that others are also created that know what is good and what is bad. Is he only referring to the angels? I don’t know.
So, in conclusion, yes, I think that not only do the laws of mathematics states that others must exist in the universe, but more importantly, that God himself has informed you about some of them. Of course I could certainly be wrong and I would appreciate a priestly or more official view on the matter.
Thank you
