You misread the Bible. Gen. 1.1 God created perfectly. It doesn't say how long it took. The universe is only 13.7 billion years old, not trillions. And it was 6000 years ago when God created the first God-conscious man when He breathed in the breath of life directly creating man's spirit which when made contact with the body man became a living soul. We know aliens don't exist because no life can exist on another planet. There are over 800 variables required for life to exist on another planet. There is not enough planets in the universe to make that possible.
