No.
I wouldn't expect you to believe it.
Given a gravity only model, the odds are outrageous.
Trillions upon trillions to one.

Have you worked with computer simulations much?
They need to be evaluated to determine how closely the model they portray depicts the real world. So, until we obtain observational evidence to show that a model does in fact predict what will happen in the real world, the predictions by the computer simulation could be accurate or they could be inaccurate.
I've worked with finite element analysis modeling to predict the behavior of objects under load in a computer simulation. Then built the actual objects, applied a load to them, and evaluated how well the computer simulation predicted the actual behavior of the physical object.
From this I've learned that computer simulation models can be grossly inaccurate, or they can be extremely accurate. But the only way I know of to obtain the latter, is to refine the computer simulation based on seeing how well it predicts real-world observations. Without such refinement, I don't have a lot of confidence in computer simulations. They may be right or they may be wrong, if they haven't been correlated with real world observations.
But based on what we see of star formation in some dust clouds, when I put my 10-year old hat on as you suggest, clumps of dust forming from gravitational attraction that can ultimately form planets seems quite logical to me.
Stars popping out planets like a hen laying eggs seems much less likely to me.
As the references Phage posted suggest, I think we are finding that planetary formation is not necessarily such a simple process, with the way retrograde orbit planets are found.
If the star was just popping out planets as your theory suggests, would 50% of the planets have retrograde orbits and 50% standard orbits? And I'm not sure how the planets get their rotational intertia in your theory, if it's a retrograde orbit, can you explain that?
Anyway the percentage of retrograde orbit planets found is well below 50%, right?
Maybe we can observe planetary systems forming someday. Or perhaps we already have. What are your thoughts on these? :

Just a random thought, for those who know a little physics: in that idiotic scenario, where a star spits out a planet as if it were a burp gun, there is no angular momentum in such system. So you can't possibly form a Solar system and/or explain the ecliptic plane.

There is only one theory that meets all observations without violating any laws of physics and agrees with all our observations. Planets are born – just like everything else in this universe.
A theory is usually based on observation and experiments. The standard model of physics agrees with everything Einstein has said. It is only in quantum mechanics where Einstein's theories do not work. Does your theory fits in with quantum mechanics ie. does it unify Einsteins's theory of gravity and quantum mechanics?

Again, you are totally ignoring the electric force in all of this.
The planets are charged bodies in an electric field.

Ok so there's an electric field. How does this impart angular momentum, usually the same direction as the star's rotation, and sometimes retrograde?

No, the odds of so many gas giants being so close to their parent star.

...you went beyond cherry-picking of facts and graduated to ignoring the content of your own sources altogether! Congratulations!
The methods of observing exo-planets are heavily biased towards system where the planet is (a) massive (b) close to the star. Ergo, scientists peering into the Universe mostly see these things.
Imagine somebody spilled a large bag of pennies in a very dark alley, which however does have a few lamp posts. Now, somebody tasks you to collect as many pennies as you can. You indeed pick a few and proudly pronounce that you discovered that pennies are product of electric light, because in most cases you found these coins in a bright spot near a lamp post. Yes, that's how silly you sound.

Is that diagram showing that the planet ejected would rotate about its own axis? Or that it would orbit around the star?
