Now if you think SETI is scientific. what do you think of methodology used to try to detect extraterrestrial life? Is scientific as well?

Okay let me dismantle your example of thunder and god of the gaps argument because I need to clear this up to avoid repetitive misunderstanding. In the past, people could not produce electricity, so for them to claim a thunder was made by god is false. It was just an argument from ignorance and God of the Gaps argument
So what would be a good analogy of how thunders happens ? Well nowadays, people can produce electricity indirectly. We can see engineers build a system that consist of a compressor, turbine and generator and by using natural laws of nature like Faradays law, they could produce electricity. So what is the source of electricity? It is the fined tuned system built by the engineers
So they just built a fine tuned system that could produce electricity. So when we compare this with the fine tuning of the universe, we can find a designer that produced a system that has fined tuned laws of nature and a material universe. Without the fine tuning of the laws of nature, life would not be there and the formation of natural phenomenon like thunders would not happen. The same thing with electricity generator, if the system was not fine-tuned, it would fail to generate electricity and plant equipment would fail to operate leading to economic losses. So we can see here that a designer is indirectly involved in thunders as engineers indirectly involved in producing electricity. The source of the electricity is not the engineers but the fine-tuned system

Well what about information. What is the source of information? Books for example contains papers, ink and information. The ink and paper are of material origin but the information is not. Because the source of information in any writings is the mind of the author who wrote it down. So we can form a general statement/theory here that the source of information is a mind. This is direct relationship unlike the previous example of electricity

So now you can see here that intelligent design theory is not just some random argument that was put there to explain anything to serve the agenda of religious people and satisfy their preference. The theory has scientific basis and you should try to falsify its arguments. Because if we kept throwing accusation at each other, we would not have any professional discussion in this matter. Yea the theory of intelligent design has implications of god. But the design theorists did not say anything about the identity of the designer because its beyond the scope of the theory. The designer might be the Abrahamic god, the Hindu god, Zeus, unicorn, fairies, aliens or whatever you have in your mind, it is a matter of your preference and has to do nothing with our discussion. And I don’t deny there might be some bias in such topics. But with agreed foundation of logic and science, it is inevitable that we would agree in some points no matter how biased we might be
