Number one: thousands of people were not working on it. Vice-president Truman didn't even know about it until after he was sworn in.

A minimal number of people were working on it, and even fewer who weren't knew about it.

And it still leaked to the Soviets before too long.

Keeping it a secret would be harder than actually just doing it.

Sorry.
