A good non-atheist, for example, a Christian, does good in a bid to get into heaven and escape hell.
That's a bad example of a good non-atheist. A good atheist would sacrifice himself to go to hell for somebody he loves to go to heaven, without thinking he will be saved for the massive sacrifice. But of course, that'd be hard for me, because I can't control my mind not to think about "you're doing this for your own good". Meh, sometimes I force myself to be good and force myself to ignore those thoughts. It's all about control.
But let's go nuts
According to some scientists, 3D is not the last dimension. Actually many scientists believe that there is a 4th dimension, 5th dimension... and so on. I watched a documentary some time ago, I don't remember much. But I remember that in 3rd dimension we can modify physical things, like mass,distance etc... but we don't have access to time. We're like in a circle, we need a lot of force to escape that circle(maybe it's the speed of light? or maybe wormholes are the answer, if they don't make you a twisted sandwich). Also, if I were in the 4th dimension, when standing in front of a an object, say... a cube, I'd see not only the faces in front of me. I'd see all of those faces.
Maybe our protecting entity, God, is in the 4th dimension, he can modify time(thus being forever) and
can see everything when watching earth.
God forgive me, I'm a little heretic right now, but not only me sees God as a protecting entity.
But maybe there are a lot of things that control our destiny.... where does mass come from? Seriously, what if our brain actually "thinks" with a non-mass energy?
Sorry, I like to discuss these things with you. I find it challenging,funny ,interesting and I find new things
