I have a very radical idea.

In Attack of the Clones, it’s implied that the Sith are behind the creation of the Clone Army, and therefore behind the Clone Wars. Now, since the Sith wanted the war, then it’s obvious that their plan was to conduct the Jedi to the Clone Army. So, the fact that the Jedi discovered the Clone Army was not a coincidence. It was precisely what the Sith wanted, and that’s why they intentionally conducted the Jedi on Kamino, and then on Geonosis. But unfortunately Lucas is not a good writer, and therefore this is not very clear in Attack of the Clones - so much so that a lot of people still think that the discovery of the Clone Army was a coincidence. Therefore, I have thought about an idea that could make it even more clear.

After Obi-Wan ends his conversation with Jango Fett and leaves the room, we don’t have Jango telling Boba: “Pack your things, we are leaving.” Instead, we have him calling Count Dooku and telling him that a Jedi arrived on Kamino, and is suspicious. Then, we have Dooku replying by saying something along the lines of: “Good. Now come here to Geonosis, and make sure the Jedi follows you.”

This way, it’s even more implied that the discovery of both the Clone Army and the Droid Army was not a coincidence, as the Sith wanted the Jedi to discover both armies in order to make the war possible.
