?How should we know the creator

The answer simply and shortly is: We don't have to recognize God through His creatures' behaviors or knowledge, but through Him.

We always have to ask ourselves:
1- How does God describe Himself to us?
2- How does god deal with His creatures?
3- Can anyone describe God to us better than Him?

And many questions like these. In reality, we have to recognize God through Him because He is the only knower of His truth completely, and He never mistakes when He explains that truth.

But the creatures always have mistakes in their behaviors, and their knowledge often is confused.

Therefor those behaviors and knowledge can't discover godly truth for us. Just the creator can. ‎
