The US has admitted the three UFOs shot down over the weekend could be "benign".
The three flying objects gunned down by the US military over the weekend may be "tied to commercial or research entities and therefore benign", according to White House spokesman John Kirby.
Officials in the US and Canada have not recovered any of the wreckage from the three balloons shot down, after concerns they were linked to China.
China denied the balloon, which was shot down by a US fighter jet off South Carolina earlier this month, was being used for spying.
They said the balloon was being used for metrological purposes and it had simply blown off course.
China accused the US of "a trigger-happy overreaction".
Mr Kirby revealed during Tuesday's press conference it will be difficult to find the motive or origin behind the three UFOs shot down over Alaska, Canada and Michigan until the debris is recovered and analysed.
He said: "We haven't seen any indication or anything that points specifically to the idea that these three objects were part of the PRC's [People's Republic of China] spying programme.
The White House National Security Council told journalists "or that they were definitively involved in external intelligence collection efforts".
US intelligence will study the debris but he revealed "these could be balloons that were simply tied to commercial or research entities and therefore benign".
However, no company or country has come out and claimed the flying objects.
The news comes after Chairman of the Joint Chiefs of Staff Mark Milley revealed the most recent strike over Lake Huron missed its target.
A "small, metallic balloon" was spotted floating over Lake Huron in Michigan, US, on Monday, which President Biden ordered to be shot down.
However, the military missed in its first attempt and had to deploy a second Sidewinder, which hit the target, but it is unsure where the first missile landed over Lake Huron.
It was revealed the US spent nearly $1million (£822,000) on two missile attempts.
Mr Milley said: "First shot missed. Second shot hit. We go to great lengths to make sure that the airspace is clear and the backdrop is clear up to the max effective range of the missile.
"And in this case, the missiles land, or the missile landed, harmlessly in the water of Lake Huron."
Wang Wenbin, a spokesman for China's Ministry of Foreign Affairs, hit out at America's response to spending nearly $1million on firing a balloon.
He said: "Many in the US have been asking, 'what good can such costly action possibly bring to the US and its taxpayers?'"
