If you're wondering about whether Creator God exists, well, good. That's all God asks you to do.
"For this is what the Lord says - He who created the material universe, He is God; He who fashioned and made the earth, He founded it; He did not create it to be empty, like all the other heavenly bodies, but formed it in such a way that it would be inhabited - He says: “I am the Lord, and there is no other. I have not spoken in secret, from somewhere in the outer reaches of darkness; I have not said to people, ‘Seek me in vain.’ I, the Lord, speak the truth; I declare what is right.” Isaiah 45:18,19
Just think about it with an open mind. Do that, and Creator God will begin to open your mind to the truth of His existence. In reality our Creator has made it nearly impossible to not think about Him.
As stated above, He has given us a material universe that proclaims day and night the reality of His existence. For if God did not exist, nothing would exist. Matter as we know, cannot create itself.
No process that is required for our universe to exist, and for life upon this planet to exist has ever – EVER – been observed, tested or verified via the scientific method.
. matter is not eternal
. matter cannot create itself
Either matter is eternal (and it's not) or the immaterial Creator of matter is eternal. It's one or the other and it's not the former.
Just think about it!
