<<It is perfectly reasonable to tell children what we know so far, while admitting that there are lots of things we don't know>>
But Chakka, they don't. Young children read, say for example a book about birds, and it says "Birds evolved over millions of years from lizards", or "wings evolved over millions of years".
These are stated to children as facts, and they are never told that they are not known for sure.
And isn't there enough wonderful known facts to tell kids about the different kinds of animals without mentioning evolution? Can that not wait to later in life when the child can reason if the evidence bears up or not?
Personally I don't think either creation or evolution should be taught in science classes. For two reasons.
One, they are both religious beliefs. And two, if we take Creation, or the 'big bang' or when those first chemicals for some unprobable reason became life, they are one off, un-repeatable events.
Neither of them fall into science as they can not be observed, measured, tested, repeated, formulated etc.
I'm all for true proper science, and for proper science education, not this dead-end of evolution.
You say there are good ways for discovering when the universe came about. What would these be? Would I not be right in saying they are based on presumptions?
I think there are many evidences that are in favour of a young earth. The problem is since mainstream science has been hijacked by evolutionary thinking these don't get the chance of public notice.
