Some believe that the universe was created by a supreme entity or it is an atom in the thumbnail of a giant. A seemingly immutable impossibility but, technically since they can't be dis-proven, both are possible.
No.
You are still confusing not knowing whether something is impossible with that something being possible. Being unable to disprove something does not imply that it is true.
For example, there are many things in mathematics that are proven to be mathematically impossible. But they were still mathematically impossible even before the mathematical proofs were formally produced.
