Can Satan create? If so, did he make dinosaurs and were they evil so they could not go on the ark?

One of the problems with Satan is that a lot of what we think we know about him is popular mythology – meaning that we get our ideas from stories and history and traditions that are not in the Bible. That Satan is a mean dude in a red suit with a pitchfork is a good example of a description of Satan that is not in the Bible. Another idea – a surprising one - is that Satan is in hell. The Bible states that he roams earth looking for someone to destroy (Job 1:6-7; 1 Peter 5:8). The point I am making is that we want to use only the Bible to understand Satan.

One of the clearest statements about Satan is Revelation 12:9, which states that “this great dragon – the ancient serpent called the Devil, or Satan, the one deceiving the whole world – was thrown down to the earth with all his angels.” There are a lot of other passages in the New Testament that also describe Satan as humanity’s deceiver, adversary and challenger. 1 Peter 5:8 makes it clear that Satan wants to destroy us and Matthew 4:1-11 is a great example which shows that not even Jesus was free of his challenges.

To answer your question directly as it refers to dinosaurs, Satan is not the Creator, God is. God is the Creator of everything, of all matter and energy and space and time and life, and everything in creation that God called first “good” and later “very good.” This includes dinosaurs! God created dinosaurs and they were good.

The reason they did not make it onto the ark was probably because they were already extinct, not because they were evil.
