I think at least for me personally, I think the reason for "less trouble having faith" in this premise is the implications of believing it. Religion asks things of you to subscribe such as Sundays, cognitive dissonance with scientific findings (not all religions, I recognize generalizations are dangerous), tithing (again, some not all), and any number of social "requirements" of belonging to the community.
Playing around with this idea asks nothing but idle brain cycles and maybe some funny looks for saying crazy sounding things. Every time this debate comes up for me I think "Oh fun, I'll go play around with this some more and see if I find anything new" and then I forget about it until next time. I don't shape my life around it, I don't make any decisions based upon it, I don't get upset if other people dismiss it or don't "believe" it, and I don't even necessarily engage with the topic every time I see it.
Based on all of the last paragraph I'd say it's even a fair question how much I do "believe" this premise at all. My answer to that is that I don't believe in it in any sort of meaningful way, it's fun though.
