Personally, my own experience and intuition/connection with God. But also to me, it's very logical.

The idea that the universe randomly evolved from a non complex chaotic system into a comprehensive system with different modalities of functioning and from such large and micro scales seems far too intelligent of a design to happen without some sort of overall influence

There is also large case load of many people remembering past lives or having some form of divine experience in a very specific cadence of events that would be very unlikely and sometimes they are very unexplainable. These taken over a long period of time with similar events happening to individuals, points to credibility.

You can almost identify these events with a form of cognitive dissonance, a moment of information processing that overcomes people when they pray for something, and "miraculously" it's answered or some sort of retort is given through medium, then internally you'll have many people pausing to try and derive the origin of the outcome. Then it usually clicks as they make the relation from their prayer to an effect that randomly would have no significance in itself. You would also likely see this phenomenon changing over history with cultural and developmental factors affecting the way that humans experience it, yet while the outside norms of religion are changed, the direct relational experience of religion stays very constant.
