ELI5: Explain Like I'm 5

Progressive creationism

Progressive creationism is a type of belief about how life on Earth began. It is similar to other religious beliefs like Creationism, but with a few differences.

It is based on belief in God, but it also says that God made the Earth and everything on it slowly over time, which means that He created different species of creatures and plants that changed over time. This means that animals like dinosaurs would have lived at the same time as other animals like tigers and lions, but then changed into different animals as time passed.

So, basically, progressive creation means that God created the Earth and all the living creatures in it over a long period of time, and that some of the animals and plants changed over time into new ones.
