This is not unique to me. If a someone personally interacted with Jesus (when he was alive), I am sure he would not need anything else to be convinced of the existence of 'the Father'.
As for myself, I have interacted with some persons such as Sathya Sai Baba and that has been enough to convince me (Here is a talk where Sam Harris mentions him
)
The actual Gods by the way are really too busy to intervene in lives of individual humans, in fact they don't even know 90% of humans by name (although they would know all about you if they ever met you). The Gods only act through their agents (or Avatars) such as Jesus. Here is a thesis written on SaiBaba in particular and Avatars in general:
