That's it. That's all, that's the entirety of the evidence. Beyond that everyone just latched onto it as 'yeah, that sounds good'.
Ignoring the fact that the incident you describe is fairly GOOD evidence(you do a thing that you have always been able to do but have never defined, and the being in the universe with the most knowledge of dynamis identifies it as such), theres another bit of evidence earlier on. During your time in Elpis(i believe its the conversation where you first find the Elpis flowers) theres a bit of dialogue that implies a connection between your ability to overcome your limits and dynamis.
