Because dodo birds became extinct about 400 years ago, so therefore none survived. Therefore, if something's "dead as a dodo," it's undeniably dead.
The phrase "Dead as a dodo" refers to the extinct dodo bird. Native to Mauritius, the dodo became extinct in the late 17th century due to hunting and habitat destruction by humans.
The saying "dead as a dodo" came from the fact that the dodo became a symbol of extinction of a species. Within 70-90 years of the dodo being discovered, it had been hunted and preyed to extinction. The saying "dead as a dodo" had a finality about it - it was irreversibly, undeniably dead, and there was no hope.
The dodo has been extinct since the 17th century. Hence the phrase, 'dead as a dodo'.
Another saying for "dead as a dodo" would be "dead as a doornail."
