I find it fascinating that people can believe in an all powerful creator God, yet deny the existence of His living creations throughout the universe.
There may be life on other planets. But mankind, arguably, is far different than other life forms. Laying aside all the moral and spiritual issues, mankind is different if for no other reason then we feel we’re the “caretakers” of this planet. No other life form feels this type of responsibility. This, btw, happens to be the exact purpose God gave mankind in Genesis.
It is reasonable to assume there may be life on other planets. We may perhaps find an amoeba floating around in a pool of water, but no one will ever find life as unique as mankind.
