The most important thing we need to believe as Christians is the first verse of Genesis, and that's the whole enchilada. That's the fundamental principle in all of this. It's a solid truth, and someday we'll likely know the whole truth about all of this.
I'm not a Darwinist at all, but forcing people to believe in a young earth is not only not necessary, it's flat out wrong.
Agreed. It is adiaphora - not necessary for salvation.
