As we explore deeper and deeper into space, we are not finding any signs of alien life. As physicist Enrico Fermie quipped, Where is Everybody? For an evolutionist, the search for alien life is the search for his own origins. We believe we are conducting the most profound search in human history to know our beginnings and our place among the stars, declares the SETI institute.
Let me suggest that without alien life forms on other planets evolution from common descent becomes less believable. If earth is not uniquely qualified or designed for life then life should have evolved simultaneous on other planets. And if earth is uniquely qualified for life then that confirms the Bible's creation account. The Bible tells us that through creation the earth is where Gods attention and plan for life is. The Bible says that Christ become a man, not an alien and is seated at the right hand of the Father, not ministering to aliens. The Bible is confirmed again.
I don't think you realize just how
vast and huge our universe is coupled by the incalculable distances (even for light years) that which objects and galaxies can be apart from one another.
For what has been studied and developed in the span of all human history and technology so far, we haven't even yet begun to explore any areas in the least. The areas we do know about are barely minuscule in regards to what information we can derive from our sojourns and observations at this point and arguably our technology is still "too primitive" to effectively search for and to properly ascertain signs of life. I feel its only a matter of time though coupled with future scientific advancements before the first living organism is discovered even if it happens to be a microscopic fungus type or a type of algae. I personally think life in general is fairly common in the universe. All we need to do is to know exactly where and what to look for. Already there has been numerous discoveries of earth-like planets in what is deemed as the habitable zone around various parent star(s). We just need to find ways to make things clearer.
Even in our own back yard involving "super close" bodies in our solar system like Europa, Titan, Jupiter, and Mars just to name a few, we may very well find something in our respective lifetimes.
My immediate personal favorites for the first evidences of life to be discovered whether fossilized or living, are Mars and Europa.
