If Yuri is indeed God Serena I'm going to flip some tables.
As Darklight stated, there is no way Warrod would not recognize him. Sure, you could argue that we never saw his reaction because they didn't face each other so far. But his reaction when being told that God Serena now is a Spriggan would have been more intense, shocked.
Secondly: Makarov. As far as we got to know Yuri, he deeply cares for his friends and family. Do you really think that he would abandon his three year old child, disappearing without a clue? If he didn't, Makarov should know about him. If he did, it would be OOC.
Mavis would also know by now I guess.
Jumping to conclusions just because the shadow (we didn't see Serena in detail) looks similar to Yuri is way too fast. Especially since he seems to be aging (look at the tiny differences in his appearance).
So far, there is no reason for him to be alive. Adding him and creating kind of a love triangle with Yuri - Mavis - Zeref would be horrible storytelling. He just doesn't fit in.
If Serena is going to be a new character, please remind me to remind you that you were wrong ('cause you seem to like this competition "Who's going to be right" and to remind people that they were wrong like you are the all-knowing little devil, sitting on Mashima's shoulder the whole time and it was just so easy to predict... seriously...).
Summed it up perfectly
