Not perfectly. SPECULATIVELY. They don't have an image of it. They don't have a clue what it's actually made of. It's all guesses. Did it come from a Pluto like planet? Eh, maybe. Formed from ice crystal and Nebula? Eh, maybe. It's an alien probe? Eh, maybe. The Alien theory may be speculative, but it also makes PERFECT sense. Just saying.
