Look at it from a mathematical perspective, if the universe is infinite, or near infinite, we should assume from a statistical approach that there must be an arrangement of atoms elsewhere in the universe which makes up other forms of life. They might not even be carbon based like us, but it would be a statistical improbability that we'd be alone in the universe.
What's most likely is that, yes there are other forms of life, both intelligent and non-intelligent, but no they've never been here since the universe is vastly large and most of it is empty.
The only teeth strong enough to eat other teeth.
