Consider two statements:
1. “The theory of intelligent design holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection. ”
2. “The Search for Extraterrestrial Intelligence (SETI) holds that if certain types of features occur within signals received from outer space, they are best explained by an intelligent cause, not as the result of just natural physical phenomenon.”
Why is the second considered scientifically acceptable, but the first is not?
