planet Earth

Evolution theory requires the Earth to be at between four and five billion years old. But no one knows how old the Earth really is. We have no way to produce an accurate measure of the age of the Earth.

Most people just assume the Earth to be very old. Evolutionists require the Earth to be at least four billion years old because their theory requires a huge amount of time for the Earth and all its living creatures to evolve.
Christians don't really need to put a time on the age of the Earth, at least those who accept the Genesis version of Creation. They can accept a very young Earth because that is what the Christian Bible says.

Science and the age of the Earth?

Planet Earth might look old but there are many factors which indicate that it could be a lot younger than the evolutionists accepts.

The geological evidence for a young Earth

There are several ways in which geological evidence supports the concept of a 'young' Earth.
