Not necessarily, if you consider other ancient writings used universal language when describing something less than the whole world.
AiG makes a pretty compelling argument for a global interpretation:
Let me urge you to read carefully Genesis 6-9—chapters dealing with the Flood. If God was really trying to describe a local flood, He surely could have written a little more clearly, for over and over again the wording demands a global flood. In fact, I have counted more than 100 times when the wording implies a global flood. It is true that some of the individual words could be understood in a local sense, but in the context, no other position than that of a global flood is defensible. Consider these few quotes of the many: ‘the face of the earth (i.e. planet)’ (6:1); ‘end of all flesh. . . the earth is filled with violence . . . I will destroy them with the earth’ (6:13); ‘destroy all flesh wherein is the breath of life, from under heaven, and everything that is in the earth shall die’ (6:17). If God had intended to describe a global world-destroying flood, He couldn’t have said it any more clearly.
Furthermore, God promised never to send another flood like Noah’s Flood (9:11,15), but there have been many local floods, even regional floods, since Noah’s time. If Noah’s Flood was only local, then God lied to us. Likewise, there was no need for Noah to build an ark for his survival. He had up to 120 years’ warning (6:3), long enough to walk anywhere on the earth, certainly out of the region of the coming local flood.

But very clearly the things that are predicted by a global flood, like present day species distributions congruent with origins in eastern Anatolia, are not cashed out in observation. There was no global flood.
