Since there is no evidence whatsoever of aliens at this point, it follows logically that there is no evidence of alien respiratory systems.
No. Seeing an alien is probably as likely as seeing an albino lobster.
None whatsoever.
We don't know it was 103 years ago. There is no evidence of alien involvement at Tunguska.
There is no confirmed evidence in favour of this.
I don't think so seeing it is illegal.
No evidence has proven that alien races exist, but if they do they may have repto-insectoid characteristics.
There is no evidence of any kind to support the idea.
There is no evidence to support such an event-just speculation.
There has not been any evidence of alien life so I do not know what you are talking about.

If you find something that looks alien, it is more than likely going to be fake. Aliens have never landed on earth and people on started seeing UFOs and aliens in the 1950s when Sci-fi came out introuducing the possibility of aliens however all recorded alien finds have been proved as fake.
