For me, this conversation ended awhile ago, so I don't even remember what we were originally discussing, but we clearly don't have "the same God" - I don't "have" a god at all (because apparently you can possess a god, because simply believing in one that encompasses the entire world isn't enough for people, the god you believe in must be *yours*), so clearly, no, we don't have the same god. I've never pretended to believe in any higher power. I see the sun as the work of hydrogen and helium working together according to the laws of physics, the nighttime stars as age-old rays of visible light penetrating the atmosphere and everything polluting it, and every tree and blade of grass alive as the work of a seed, of something else, potentially just a few inches away from me or potentially miles upon miles away, in another state or country or wherever. Every living being is the product of other living beings of the past. I don't see these things as miracles of a god but as simple facts of living on a habitable planet - facts I appreciate and celebrate no less than you do even without a god.
You're welcome to be religious. I won't attempt to take that from you, and if I do, call me out on it. You're also welcome to question the Jewish faith as a whole, though that's incredibly misguided. There are so many devout Jews that take the word of Torah and Tanach among other scriptures to be the word of law, so many that take it to be a guiding power in their lives, so many that believe every story written no matter how fantastical they are.
The Jewish faith isn't lacking; it's changing, just as other religions are. There's no reason to believe that it's dying, and people that say that ought to realize that religion is a point of pride. Jews around the world identify with one another, just as people in other religions do, and provide each other a sort of social safe haven. The word of scripture doesn't have to be taken so seriously and to the letter for that to continue. If you don't see it that way, then don't live your life that way, but it's unreasonable to say that people who choose to practice their religion are somehow less faithful. Let your god decide that down the road.
