Without any other indication of what the Protheans looked like, it is reasonable for the Alliance to assume the Protheans looked like the statues that were found on Ilos. I would also say it could be plausible that the statues found on Ilos may precede the Protheans themselves but that is just my own speculation and imagination speaking. =)
