How can ID say this? My understanding is that ID has stated nothing.
Some things just follow logically. If evolution does not exist as a process, then the only source of design is God. Aliens of whatever could not have evolved, so even if were were designed by other creatures, they had to be designed by God.
Since evolution doesn't exist, nothing has undergone macro change since the original. If changes have occurred, the changes were made by God.
What are the alternatives?
