Argument against Intelligent Design

[Deesse23]

1. Intelligence is known to cause effects exhibiting information rich and specified complexity 2. The universe and life are effects that exhibit information rich and specified complexity.
3. Therefore, intelligence is a possible cause for the universe and life.

The so called "W.L. Craig fallacy": He is applying everyday intuition and common sense to an environment where it is almost certianly not applicable.

The best explanation/model we currently have for the origin of the universe we live in is, that it once was condensed in a singularity, where, according to most recent calculations the fabric of spacetime breaks down. How can "intelligence" exist, particularly without time? Intellect involves thinking, thinking involves time. How does that work without time?

What is "specified complexity"? No IDer has ever explained it without question begging afaik.

The only way a possible intelligent cause for the universe and life can be challenged at all is if there could be found a non- intelligent source that can be demonstrated to cause effects of that kind/class

He is trying to establish that ID is the "default position" for the estimated origin of the universe. It is not.
Did you already allow him to shift the burden of proof yet? If so, it was a tactical mistake on your side. You have to demonstrate shit. If he claims ID, he has to support it, thats how the game works.

Since there are no known non-intelligent sources that can demonstrate causing effects of that kind/class (even a simple cave wall drawing), intelligence stands alone as the highest probable cause for the origin of the universe and life.

Shifting of burden of proof. Bare assertion.
How did he estimate this probability?

the only known cause for effects of that kind/class are intelligent causes. Period.
