Because we are not able to explain life, especially, how if life began, what happened at that instant is proof that god exists.
What the OP wrote didn’t make sense. I will copy and paste it below.
I love to sit on my back porch in Florida and listen to the rumbling of thunder. It reminds me of God’s majesty and power. The apostle Paul said creation was the best evidence of God’s existence. He wrote, “For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen” (Rom. 1:20). Nature is actually full of quantifiable miracles. Just consider the fact that the earth is the perfect distance from the sun to support
life. If we were any farther away from the sun, we would freeze; if we were even slightly closer to it, we would burn up. It’s obvious God created this home for us!
If you didn’t know why there are several flower varieties, now you know. God created them so we could have many colours to see unless you were born blind which means god only wanted you to smell the flowers.
4. The Bible
Do we need to say anything else?
5. The global spread of Christianity
If something is believed by many people, it must definitely be true!
The amazing thing about god is that he had no qualms committing suicide to save us from himself. How obstinate are these atheists to no see this?
7. My personal friendship with God
Am convinced the moon is made of cheese. You may disbelieve everything else I say but you can’t disprove this. I have this feeling in my gut.
