I wrote this in response to a Facebook post. I could just delete it, but I thought maybe somebody else might find it useful.
If you went to Mars and found a computer lying on the ground, you would conclude immediately that somebody had been there. You would not conclude that random forces over billions of years put it together. The human body is thousands of times more complex than a computer. You can’t explain life without an intelligent being doing it.
The next question is whether this God has a relationship with what He created. Has He tried to communicate with human beings? I assert that if He had, by this time, it would have to be one of the major religions in the world today. They are all mutually contradictory so they all could not be true.
Confucianism and Buddhism aren’t really concerned with God, don’t claim to be, and are essentially only confined in a small part of the planet. Islam is new on the scene, relatively speaking, and has grown almost entirely through the use of violence.
That leaves Christianity and Judaism, with Christianity claiming to be Judaism 2.0. The one claims to fulfill the other. Is that true? Judaism is a religion based on a priesthood and animal sacrifices. All that ended in 70 A.D. There is no historical, logical, empirical, or theological reason to think that God’s program, system, or way of communicating to human beings changed into what exists today. And, besides, there is no interest among Jews to carry their message to the rest of the world.
Then there is Christianity, which is the most widespread religion in the world, where people have sacrificed everything to take the message of God’s love for people to every end of the earth. The Bible is the most widespread book in history and has been translated into every major language and maybe about 4,000 of the not-so-major ones.
