Did i just see bigfoot?!?

2 days ago i found a huge footprint in our yard! nearly 18" long! the first thing that came to my mind was bigfoot. I read online that they eat dog food if its left out so i thought that i would burry some outside. I burried it about 2" under the ground. That night i hear little knocks on the basement door. When i woke uo the next morning i walked out the door and the dog food was laying at the door. At 4:40 AM about 10 min ago i walked upstairs 2 use the bathroom and in the front yard i saw a ver huge creature on its hind legs standing straight up. It picked an apple off of our tree then the dogs barked and it ran off. I watched it go down through the fields and before going into the woods it turned around,at this point i was standing at the tree it picked the apple off of,and looked right at me.what was it! it ran on its hind legs all the way to the woods!
