Articles like this that say “rewrite history”  are really beginning to annoy me.  The discovery that could rewrite Australian history

McIntosh believes that the coins may indicate that there were maritime trading routes connecting east Africa, Arabia, India and the Spice Islands over 1,000 years ago – much earlier than first thought. If this theory is proved correct it will mean that other civilisations discovered and made contact with Australia six centuries before the Europeans.

This proves nothing. People were travelling and trading all over the place back then.  Discovery is when you map it, study it, colonize it and lay claim to it as the Europeans did.
