Typos:

Agent should generally be capitalized when referring to a specific person, as it's a title: Agent Bridgewater, Agent Reid, etc. There are lots of these here so I won't flag each one.

paragraph 1: proposedly extraterrestrial -> proposedly-extraterrestrial, spent -> spend
paragraph 2: gueule". -> gueule." (Periods should go on the inside of quotes.)
paragraph 4: Read -> Reid, added: -> added (Colon is unnecessary.)
paragraph 5: partner agent Bridgewater -> partner, Agent Bridgewater, agent Bridgewater and me -> Agent Bridgewater and I
paragraph 6: Dutch Randstad Conurbation is all capitalized here while "conurbation" isn't twice above. Not sure which way you want it but it should be consistent. chatter -> chat
paragraph 7: disbelieve -> disbelief
paragraph 10: plain -> plane, how the toll -> the toll
paragraph 13: plain -> plane, aircrafts -> aircraft, Spanish speaking -> Spanish-speaking
paragraph 20: sighed opened -> sighed, opened
paragraph 21: extra space at the beginning. gasses -> gases (twice)
paragraph 22: extra space at the end of the first sentence. inter-glacial -> inter-glacial period
paragraph 23: better educated -> better-educated
paragraph 24: much and much worse -> much, much worse
paragraph 25: guy that -> guy who, if Grizzly is just the bear rather than something special in your world it should not be capitalized.
paragraph 28: Our job now to gather -> Our job now is to gather
