How do you deal with life now that you are an atheist? (With a little of my life)

I'll give it one last go. This is how science works:

1) Observe
2) Create a hypothetical predictive model
3) Test the model repeatedly
4) If the model is proving unreliable, go back to step 2 and improve it.
5) Get other people to review your work and test your model. If problems are found, go back to step 2 and improve it.
6) You have a working, practical model.

You have got as far as step 2. You have a hypothetical model. Let's say you can run a test T on a universe and it produced two results, D and N.

For a universe U, the model predicts U is designed if T(U) = D, and it predicts U is not designed if T(U) = N.

Now onto stage 3. Test the model repeatedly to see how accurate it is. In this case, we need lots of different universes, some designed, some not. We then need to run the test on them, to see whether the predictive model is accurate or not. If we get flawless accuracy over a very large number of test subjects, with the model successfully separating the designed universes from the non-designed ones, then we can say we have a working, practical model, if the results are confirmed by stage 4.

Then we take this model and apply it to our universe, being confident that the result is probably accurate.

You have omitted the whole of the procedure in italics. You've simply assumed your model is correct, after no testing whatsoever. And of course, you have left it out precisely because we don't have access to large numbers of universes. We have this one. We have nothing to compare it to, except bits of itself, and models based on itself.

Thanks for the structure and procedure.
