"I wonder how many of the people cheerleading for indefinite lifespan technology also believe in heaven."

How did that turn into "a lot of people"? Whether it is 1% or 90% doesn't enter into my hypothetical.

Second, I didn't "reach a conclusion." I asked a sincere question, and it would be great if someone who is in that intersection gave a sincere answer.

Finally, using loaded terms like "cling" and "quite a flex" is just unnecessary attitude.
