So your dad plans before opening a hotel, therefore God exists?
Are any of your dad's hotels like "Hotel Earth" where guests randomly get killed by a wide variety of means?
Do your dad's hotels have water you can drink and water that makes your bowels explode?
The point is, the Earth doesn't show any signs of being planned. The whole universe shows no signs of being planned. There are stars exploding all over the place, whole galaxies crashing into each other, asteroids whizzing about. It's complete chaos.
Religions give rise to atheists only in specific cases. The Mormons put forward their idea of God, the atheist disproves and therefore doesn't believe in that god and so on. But everyone is born an atheist. Atheism is the baseline. It's only from there that people learn about Gods and religions. That's why if you're born in America you'll most likely be a Christian. If you're born in Pakistan you'll be a Muslim.
If humans started off with knowledge of God then there would either only be one religion or the religions would be evenly mixed across the globe.
