The possibility for a god to exist?
I agree. But think that logic through, does the simple possibility make it the truth? Of course not. There is a possibility invisible beings exist that we just can't detect... but is there any proof of that? No. That's why we don't take such possibilities seriously. If there is any such thing that exists that we just can't detect, like a god would be, as admitted by believers "God is outside space and time", then what's it matter?
Furthermore, the moral issues behind such propositions is a whole other issue I believe contradicts there ever existing such a being to "protect" humanity. The god of the OT and many followers of religious figures, be them Christian, Muslim, Jewish, etc. are dangerous people with dangerous ideas.
I'm interested in what you believe. You say you're not religious, you don't follow a religion, right?
So what do you believe in? Do you believe any gods exist? Are you an atheist?
Good question! I applaud you for asking.
This bit is from wikipedia;
Redshifts are attributable to three different physical effects. The first discovered was the
Doppler effect, familiar in the changes in the apparent
pitches of sirens and
frequency of the
sound waves emitted by speeding vehicles; an observed redshift due to the Doppler effect occurs whenever a light source moves away from an observer.
Cosmological redshift is seen due to the
expansion of the universe, and sufficiently distant light sources (generally more than a few million
light years away) show redshift corresponding to the rate of increase of their distance from Earth. Finally,
gravitational redshifts are a
relativistic effect observed in electromagnetic radiation moving out of
gravitational fields. Conversely, a
decrease in wavelength is called
blue shift and is generally seen when a light-emitting object moves toward an observer or when electromagnetic radiation moves into a gravitational field.
So basically since we can observe other galaxies light years away from us with our telescopes and each one of them is emitting a light that is on the red side of the spectrum, we can accurately conclude that each galaxy is moving away from us at an increasing rate, in other words, the universe is expanding. If you use that knowledge and apply it going backwards in time, like a movie playing in reverse, you will find that all the matter that is in existence was at one point all in the same place. This is huge evidence to support the big bang theory and the expanding universe theory.
