I think you may be confusing random effect for cause and effect. Quantum events have cause for every effect. Say a virtual particle pops into existence, that particles twin is the cause for the effect of the emerged particle.
You are using an extremely odd notion of cause, and also one which completely undermines your argument. Suppose I posit "The cause of the universe is the twin of the universe" and - bam - there's no reason to follow your argument to your desired conclusion.
Also, I note you gave no response to your argument being based on the fallacy of composition?
I asked for 10 true examples to offset hundreds of thousands if not millions of examples that support cause and effect. I wasn't being mean and only suggested ten as a means to show that the my claim was more rational than yours.
I don't need ten, or two, I need one. With just one example your premise is shot. You've presented a logical premise regarding
all events; if just one event does not have a cause, your premise is false.
As it happens we know of a great many examples of uncaused events (note, here, I use the normal definition of cause, not the bizarre notion you put forward above); quantum mechanics spits them out all over the place, and they go on all around us.
While it may sound grossly counter intuitive to say that cause and effect does not require time, it is an accurate claim. Physicists do not look at time in the same way as most laypeople. In reality an egg should break as easily as it "un-breaks". Physical processes at the microscopic level are thought to be either entirely or mostly time symmetric, which means that the theoretical statements which describe them remain true if the direction of time is reversed. So cause and effect is not time dependent.
Physicists do not look at time how you think they do. But let us accept that a cause need not be temporally prior to its effect, then your argument again crumbles. If causes do not need to be prior to their effects, then there is no reason to suppose that the cause of the universe is prior to it, and without a timeline to staple your argument to it fails because any cause can happen any time we do not need a cause outside of the universe. Maybe the universe caused itself?
