Voldemort most likely intended to make a Horcrux from killing when he went to Godric's Hollow. Using the death of the person prophecied to kill him to guarantee his eternal life has obvious appeal.
Therefore, he will have done whatever spells and rituals were necessary to create an Horcrux. The only missing component was a death, and there was a death that night.
It seems plausible enough that this could have created an Horcrux, as Voldemort intended, but not out of the intended object.
It would also explain the mental link between Harry and Voldemort, and why Haryy can speak Parseltongue.
