I think that the current outbreak of creationism is an honest psychological reflex.
We have an inborn desire to survive and share this with most of nature. I would point out that this sun of ours has another five billion years on it before it turns to a red giant (I believe). Due to increased output from the sun, life on this planet has only about another billion years unless we can find a way to shift our orbit further out (don't laugh, there are theories on how to do this). Furthermore, an asteroid could plow right into the earth creating immediate untold death and significant climate change. Add into this the fact that climate change induced by human activity has basically insured that our civilization will have to transform itself or die. Hurricanes could hit. A black hole could shimmy its way through our solar system.
Humanity has been confronted with a sickness. We used to be at the center of a rather small, purposeful universe. The sun and planets went around us. The stars were placed lovingly in the sky to provide regular guides for ships and to decorate our night. God was in Heaven and from His throne He had His eye steadily fixed upon us.
Copernicus and Galileo figured out that it wasn't so. The earth instead floated around the Sun - suspended by no visible force no less! Then Newton comes along and starts talking about gravity. Some natural force keeps this planet in movement and not the hand of God. Then this Darwin fellow comes along and demolishes literal belief in the six day creation. Instead, countless eons have come and gone, forms of life have arisen and gone extinct, seemingly without purpose. We find out that our ancestry is rooted in the same ancestry as all of life. That our formation wasn't a special creation, it was the result of a process. A long and ugly natural process. Now, as we turn our eyes out to the vastness of space we're confronted with dread. The Universe is unimaginably big - why would God create a universe this big solely to put human beings into the picture? And if there is life on other planets, doesn't that make us far less special? Why have all of these forms of life arisen and fallen, never to rise again? What meaning did that have?
The Universe is too big to solely exist so that Jesus Christ might come into the world and save it. The same holds true of providing a forum for Moses or Muhammad.
I am not an atheist, but I think that anyone who is going to affirm any sort of spiritual reality, has to consider the possibilities and problems that scientific understanding introduces into the picture.
I think we have to confront these realities and find a way of experiencing God/the Divine/the Foundational Spirit/the Unmoved Mover in a way that accepts the world around us. For me, the fact of evolution through adaptation means that adaptation is the way for us to deal with new understanding. We ought to be feeding the poor, stimulating education, trying to discover how this universe of ours works, and find new ways to explore it. If we keep pulling the blanket over our heads to hide from the bugbears, praying that Daddy's going to save us, we're screwed. Look at what we're currently doing to the planet and to each other.
That doesn't mean that faith is, in and of itself, evil. However, it does mean faith married to a juvenile mindset is. It's time the human race grew the hell up and took charge of our future and started being honest about these ultimate questions.
No, I don't know if we go on forever. I have no idea if we're reborn. I don't know for a fact that the universe will ultimately die, or that humanity will be in the solar system (at least solely) when our Sun goes up in a big ball of fire, or that we won't make it through global climate change. I do know that no one is coming to save us from it, though.
Pardon my rambling, but creationism usually has a worldview that comes along with it, so I addressed it as a whole.
All the best,
