Wind Shlavitor,
We dont know if a slug is programmed or not.
What is the difference between the brain of a snail and the brain of a man? Nothing other than scale. A snail sees shade and decides to crawl there to get out of the sun. A human sees shade and decides to walk there to get out of the sun. The only difference is that man has a more complex brain that allows him to 'reason' at a much higher level.
Snails are much 'smarter' than robots. Scientists have a very difficult time getting robots to guide themselves through a room (they cant process what they see and use it to make decisions), though animals from humans to mice easily do this unconciously. The brain of all animals allows them to make decisions about their environment, and just because man's decision making is much more complicated than that of a snail doesnt mean that there is a disconnect in evolution.
There is no evidence for God's existence, and there is no evidence for god's non-existence. That leaves only speculation.
There is a supernatural being that watches over us but we cannot detect him.
There is an invisible dragon that watches over us but we cannot detect him.
What is the difference between these two statements? You believe one to be plausible (supernatural being) and one not to be plausible (invisible dragon). What is the criteria in which you judge 'supernatural' things as being possible and not possible?
