How likely is the discovery of alien technology by Avi Loeb?

 Avi Loeb, a physicist from Harvard University in the US, has recovered 50 tiny spherical iron fragments from the bottom of the Pacific Ocean that he claims may be material from an interstellar alien spaceship.

Loeb is linking his finding with the passage of a fireball in January 2014. The meteor was observed by sensors of the US Department of Defense that track all objects entering the Earth’s atmosphere. It was recorded as travelling faster than most meteors and eventually broke up over the South Pacific Ocean near Papua New Guinea.

Data on the object is held by Nasa’s Centre for Near Earth Object Studies (CNEOS). The meteor’s official name is CNEOS 20140108, and is also referred to as IM1 (for interstellar meteor).

There is a very large scientific leap from observing a fireball to claiming it is an alien spaceship. What is the evidence on which Loeb bases the claim? And how likely is it to be true?...<<<Read More>>>...
