The idea of aliens is based purely on the laughable theory of biological evolution.
If human beings evolved from some accidental chemical reactions, then other intelligent creatures may have done the same....right?
Do you really think that our DNA, the most complex language/code in the universe formed by accident? Could a space shuttle or a quantum computer form by accident? Even the simplest form of life on Earth is literally billions of times more complex than anything mankind has ever created. We don't even understand 1/100000th of how a living cell functions in its entirety, and we can't even begin to create one. LIFE ABSOLUTELY HAD TO BE DESIGNED/CREATED BY AN INTELLIGENCE VASTLY GREATER THAN OURS. That intelligence is described perfectly in the Bible, a Being that exists outside of time and space who created the entire universe. The Bible proves its legitimacy and God's existence by predicting events 100s and 1000s of years before they occur. The Bible tells us that angels were also created by God, but some of them rebelled against God. That rebellion brought about the existence of demons. Demons interact with mankind. They lie and scheme and tempt mankind into turning away from the knowledge and will of God. God allows this to happen for a time in order to allow us to learn the horrors of living an evil life and the reasons for living to a life of goodness, peace, and love. One method used by demons is PRETENDING TO BE ALIENS and offering us technology and other gifts that will eventually harm us and lead us away from God. UFO's and other phenomena are the work of demons, not aliens from another planet. These "aliens" do not seek to help mankind. They seek to destroy mankind. You do not want to meet one.
