Selenites Pack

That unit would be an "astronaut" or more specifically Dr. Cavor - Balthasar will confirm. No HG Wells martians because Balthasar took his cue from Edgar Rice Burroughs.

The similarity between them and Well's creation goes to show the impact that Well's book had on the popular imagination. One the other hand, the tradition of 'green' aliens goes back to well before Wells, even before Verne:

Location. Near Neston England
Date: July 1857
Time: evening
On the outskirts of town a young shepherd named Robert Clancy was tending his flock---and his sweetheart---when he noticed a round gleaming vessel sanding on three legs at the side of a field. A golden haired woman in unusual green clothes stood by the unearthly craft watching Clancy and his girlfriend for a while, then waved and climbed into the vehicle, which afterwards took off into the sky and headed northwards. For months afterwards, no sheep would graze on the spot where the craft had stood.

An unspecified number of witnesses watched an enormous sphere of flames land on top of a hill. Two very small occupants, about 1.20m, wearing with greenish luminous clothing exit the sphere and disappear into the woods. No other information.

Most of the 'humanoid sightings' listed from the pre-sci-fi era are either obviously religious or superstitious in nature, and some are just tragic, like the melancholy 'giant' killed by villagers. But, reading through them, there seems to be a change that occurs in the nature of the 'sightings' as the industrial age dawns. These visitors often seem to be stranded, and less supernatural, and more than a few are seen to be siphoning water into their crafts, which are often saucer or cigar shaped. This is decades before the first science fiction was actually written by anyone, if we're to accept the veracity of these accounts (I'd like to know if the originals of any of these accounts exist, for instance). Because, if some of these accounts are to be believed, they suggest time travel more than they do alien contact. Note the modern details in this account:

Location. Harayadori Japan
Date: February 22 1803
Time: unknown
Several villagers and anglers gathered on the beach to see an object, which had appeared on the shore. The object was about 20 feet in diameter, having a Saturn like shape with the upper dome apparently made out of glass, and appeared to have transparent sliding doors. The villagers looked inside the dome and saw some strange lettering and a bottle that appeared to have water inside. A very beautiful young woman was also seen inside the craft. She had pale features and had long shoulder length hair. She stepped out of the object and spoke in an unknown language; she also carried a small box, which she would not let anyone touch. Eventually she went back inside the craft and the villagers pushed it out to sea where it drifted out of sight.

Poor girl. First she couldn't get a signal on her iphone (which also had a lousy translater app), then the villagers push her out to sea. Wonder how that turned out. She's gonna wish she'd brought more than bottled water with her. That's what happens when you take daddy's time machine out for a spin....
