No your question isn't so stupid, but sometimes it happens that nobody reads a message...

OK, "stupid lamer" ...when CreateProcess creates a new process, it creates also its primary thread; so, you can obviously notice a new thread creation with no CreateThread call.

Besides, if your process calls CreateThread by runtime dynamic linking (unusual, but technically possible), the Import Table won't contain any CreateThread reference.

You aren't a stupid lamer, of course...
