Actually in a sense, they are right. If you believe in the concept that GOD creates everything, it automatically implies GOD also creates the GOD particle.
At the end of the day if you believe in creationism, you can never lose; since every shred of scientific data and evidence that proves that GOD had nothing to do with the creation of the universe; All those data and evidence, in essence is also a creation by GOD.
Therefore…
…because he can.
End of story.
