There are a number of organisms that produce jelly-like masses found on trees or the ground.

1. Nostoc. This is a cyanobacterium that is common but seldom seen except after a rain when it soaks up a lot of water and forms a jelly-like mass.
2. The inedible parts of frogs (notably the ovaries and the jelly of eggs). Birds eat female frogs and cough up the not very delicious or nutritious bits. This includes the ovaries which explode into a jelly like mass. Often found near ponds.
3. Various kinds of algae or fungi produce slime or jelly like masses, especially after a rain.
4. The jelly from amphibian eggs, minus the eggs and offspring, which have hatched and moved on.
5. Slime mold. This is an agglutination of individual slime mold cells that come together and lose their cell walls. The mass can pulsate and move slowly like something out of a horror SF movie. Problem is, slime mold is seldom clear and transparent. It is often a bright saffron yellow and moves purposely.
6. Gookum. This looks and tastes like cherry Jello(TM) in its dormant state, but when it is active, it eats anything active. (See MAD Magazine, article "Gookum!" in a reproduction of the very early comic book format issues of MAD from the early 1950s).

My bet would be on some kind of fungi. The kind that lives under ground and is very seldom seen above ground. But there are several different critters which produce "jelly" and depending on where it is found and what time of year, it might be one of several distantly related organisms.

I am very confident it has nothing to do with meteors (especially on the other side of the world) and even less to do with aliens.

The idea that it has something to do with stars or meteors is probably due to the fact that it is mysterious and found on the ground. Everything found on the ground must have fallen from the sky if you don't know what it is. Scientists refused to believe in meteorites for a very long time because of all the people who claimed to have seen rocks fall from the sky, only to produce a perfectly ordinary bit of sedimentary rock as proof.

Mind you, for quite some time scientists believed that only iron-nickel meteorites were real until somebody (probably a scientist) produced one which was definitely rocky rather than metallic (a chondrite, as they are called). And then they refused to believe in sedimentary rocks falling from the sky. We now know that many meteorites are bits of the Moon, Mars, etc. Mars has sedimentary rock, so finding a meteorite made of rock that has been processed by water is not impossible, just very, very rare. Mars rocks are worth a lot of money because we have so few of them. Chondrites can form by the aggregation of dust in space or they can be bits of planets, moons, asteroids, etc.

The blue-green lumps of gelatinous material which sometimes fall from the sky are blamed on airplanes (presumably algae or cyano-bacteria can run amuck in the ice that collects on airplanes) but there is often no evidence of an airplane flying over the location where it is found. My guess is that some of them do fall from airplanes, but others form in the upper atmosphere where updrafts can bounce largish bits of ice for days if not weeks and months. Some may form on the ground perhaps (see nostoc, above)

Remember: mysterious things found on the ground don't necessarily fall from the sky. And if they do, they don't necessarily come from meteors, space ships or airplanes. There's a lot of stuff up there in what scientists call the aeolian zone. Charles Hoy Fort came up with some wild and crazy examples, but what was part satire and part mystery in his day is now definitely within the territory of conventional science.
