This is what I think was the heart of your answer to my question: Now this god could have created the universe in such a way that it allows intelligent life. And once these lifeforms reached a certain level of intelligence he might even have decided to interact with them.
Breaking this down:
How old do you think this God might be?
If the Designer were honest then It would have to be at least 14 billion years old. Before the Big Bang time has no meaning. Indeed the phrase "Before the Big Bang" has no meaning, because time is a manifestation of the physical universe.
The Designer could be less than 14 billion years old, if the Designer is a trickster, that has created a universe (perhaps as recently as 1 second ago, while I typed the word "recently" there) with the appearance of age, in order to fool its sapient creationst. A fine joke indeed.
