One of my volunteer job friends likes to needle me about my faith in a kind of good-natured way. We co-host an astronomy/space program and he thinks that he can throw science back at me to show that God cannot exist.

Quite apart from the fact that science has no interest (nor capacity) to prove or disprove anything of the sort, he is dealing with someone who believes in science. If science wants to show what an incredible Creator we have, then it can go right ahead, I retort.

What about the Sun brightening in about 600 million years and the threat to life? How about the collision with Andromeda in about 2 billion years? How could a loving God permit such a thing? 

Anyone who looks at the planet and the human condition and thinks that that will be an issue in 500 million years is kidding themselves. We won't be needing the sun or Andromeda to put paid to life on Earth. Humans in their brokenness are doing a very fine job and that is entirely on us.
