Not all snakes do that but i swear it's a snake. I have no idea how it got there, guessing a bird maybe dropped it
Maybe you did see a snake, maybe you didn't.
This one isn't however, snakes native to this country are more likely to want to get out of your way unless you annoy it or corner it. I remember as a kid playing manhunt up the south downs, I bent down to hide and looked left to see a snake tail about 5 feet away from me slither into a bush.
It could have it bit me but it didn't.
If you want, I can tell you its a Queen Wasp
