Any truth to transformers 3 story line?

Obviously MOST of the movie was pure fiction. There are no Transformers on earth or anywhere near it. But the remnants of their previous visits are all around us. The only truly accurate and factually portrayed part of the third movie was when Sam Witwicky died and he was in robot heaven with the Primes and they told him about his destiny and he came back to life. All the rest of it is pure Hollywood, of course. Everyone knows we never set foot on the moon.
