Like in a joke about two Buddhist monks:

- What are you doing?

- Watching the trees grow.

- Always so busy...

It's an interesting and fresh turn to say we better have experience when hoping for an afterlife. Note, that we fundamentally talk about faith and hope here, which that "50%" possibilities present.

Pivoting the concept even more into Christianity. Not just any experience, but the experience of communion with God, the experience of God's presence. Whoever seeks it will not die.

"For my Father’s will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise them up at the last day.” John 6:40 (NIV)

The logic of this world can't prove or disprove that this life is not all there is (and actually, this life here is just a myriad of lives and deaths). This is where experience shines - our very own, subjective one.

However, the "problem" is that "spiritual dollars" are given gratis. There is no need to plan for the trip "to the Moon and back", in a sense. It's enough to listen first.
