That's not true. The material has been sent to multiple independent laboratories for analysis. Why are you spreading false information here? And do you understand that a thorough scientific analysis and publishing research takes time?

Edit: Since you're putting words in his mouth in an attempt to discredit the validity of the subject, here is an actual quote:

"It has material strength that is tougher than all space rock that were seen before, and catalogued by NASA," added Loeb, "We calculated its speed outside the solar system. It was 60 km per second, faster than 95% of all stars in the vicinity of the sun. The fact that it was made of materials tougher than even iron meteorites, and moving faster than 95% of all stars in the vicinity of the sun, suggested potentially it could be a spacecraft from another civilization or some technological gadget."

That's not stating definitely that he has proof of aliens. It's also the first time material from an interstellar object has been recovered on Earth. This is an exciting development for the scientific community and mankind, but it's unfortunately being convoluted by people who are too ignorant and narrow-minded to objectively consider the information.
