Thank you for sharing! I wouldn't say that your story is irrefutable proof, but it is somewhat mysterious. It is possible that the events you describe were a coincidence. I have experienced some uncanny coincidences myself that had no apparent spiritual meaning (for example, seeing an unusual frequency of references to a pop culture phenomenon over the course of a few days--I think maybe it was Scooby Doo? I don't remember for sure) so, based on personal experience, I don't think coincidences always have a deeper meaning or a spiritual cause. But sometimes they might. And certainly, people have reported apparent angelic intervention that can't be explained as coincidence.

Perhaps it's best not to think of your story as irrefutable evidence because it can become problematic if one gets into the habit of regarding every curious event as having a spiritual meaning or cause. Even if angels do intervene at times, other times there are simple coincidences. I like to keep my mind open and I find it's entirely possible to do it while also being reverent of the mysterious ways that God works in the world.
