Unfortunately that isn't a very strong argument because just because we are made up of water doesn't mean life necessarily requires it. Hell life might be something we haven't even thought of or something we may not even consider "life" at first glance.

Life doesn't necessary require water, but water is the 'universal solvent' and since life requires chemical reactions water would be the best possible solvent for those reactions.
