Alright, so point-by-point. Can't really cover everything, though...

1) All of the humans who fell were children. So a child falling down for "research reasons" wouldn't make sense. Not to mention that if the first child was indeed Gaster, then A) presumably one of the followers would have noted it, B) he would have been killed anyway since the royal decree was that any human who fell down must die, and C) his body would not be able to exist without his soul (you say later "why can't humans survive without a soul, since Flowey does," but the point you make is that humans produce determination naturally, but it is theirs souls that produce this determination, not their bodies, which is why the soul lives on when the body dies).

2) Monsters may not rely on technology as humans, but if everything they had was just junk, then things like the oven and refrigerator in Toriel's house should not exist. Monsters seem to have some capacity for constructing technology of some sort. There's no reason for rejecting out of hand any association between science and monsters.

3) Undyne's reluctance for not attacking you while you are in the grass is already explained in-game.

4) Again, the humans are all children, hence the justice soul cannot be a "man."

5) Much of what you're positing has the humans showing up throughout the Underground randomly, but this can't be the case, as all, or almost all, of the humans who fell down stayed with Toriel for some amount of time, given the children's shoes that are in Asriel's old room (Asriel doesn't wear shoes, so they can't be his).

6) There is absolutely no indication that Gaster was experimenting with souls or soul power. Alphys says specifically that she has been asked by Asgore to figure out how to break the barrier using the power of the souls. There is no mention of any previous research. If Gaster was supposed to be the first to experiment with soul power, then there should be some indication of this.

7) Much of this theory is based on the idea that the skeleton and ghost monsters are actually humans, because they resemble humans or human lore in some way. But given the sheer variety of monster types in existence, there is no reason for ruling out the concept that there could be a skeleton-type or ghost-type monster. Given that these monsters, when killed, expire in the same way as other monsters, we would basically need a theory for turning a human into a monster, which is not only never indicated in the game's universe, but would cause massive problems for the narrative, as humans would never be able to truly remove all monsters from the surface, given that dead humans would in some or another be able to turn into more monsters.
