You should try, others see it in the clouds, on the stars and on shadows, in cofee residue, in cards, even on TV when there is no signal. Also, did you try to find Mary, Pontius Pilat, Serpent, Jegova, Budda, Allah, Eve, G.W.Bush, Hitler, Alien Gonzales, and other Earth's and alien peronalities? You should work harder - if you shoot many more pictures, there will be a chance that you'll find those faces too. Espesially I would recommend to shoot clouds - they change fast thus giving you plenty of images to SELECT from.

And keep informing us about your rare footage - we just love to see faces of God(s), Bushes, etc.
