I don't see how the space-time continuum would exist at all without being formed by something/someone that can exist outside of space and time. Why is material reality even here? Why would there even be physical dimensions or matter within which anything else can occur? Something existing outside of spacetime can naturally be eternal (by its very definition), but material reality has to be created by something and is on a time continuum that you have to trace back to somewhere.
Plus I see a lot in Jesus's teachings (the real ones from the Bible and the early Church, not the corporatized rich church distortion) have wisdom and truth beyond mere human understanding.
Growing up my mom was into church but my dad didn't believe any of it, so I grew up basically ignoring all that. Decided to start following Jesus during college while I was seeking more meaning in my life than anything I had found in the secular world.
