Much is ongoing in President Donald Trump's second term, but a discovery could overshadow virtually everything.

This is what Avi Loeb, head of the UAP Science Advisory Council, said.

In an interview with AlterNet, the Harvard physicist said, “Obviously, for a president, it would be a great boon if, during his term, we discovered we’re not alone — that we have a neighbor in our cosmic environment."

He continued, “That kind of discovery would be remembered millions of years into the future. It’s not like a dispute with another nation, which in a century will likely be forgotten."

“This would be a major discovery that shapes the future of humanity,” Loeb noted.

But if such a discovery is made, the physicist said they will not care who is sitting in the White House.

“If someone arrives from the vast expanses of interstellar space, recognizing how humans divided up territory on Earth is a very low priority for them,” he said.

“They wouldn’t care about the United States, and they wouldn’t care who its president is," he added.

Loeb’s appointment drew criticism for not being nuanced enough when discussing the chances of alien life existing.

Yet, the Trump administration has released several batches of UFO files; however, it did not produce undeniable proof of extraterrestrial life.
