Sounds like you like science fiction.
It's quite easy to understand. We know at least this galaxy exists, you might know the cause of everything that is in this planet but there are still hundreds of other planets out there and millions of other objects, how do you know they have a cause?
We know through observation that some things out there have causes. The light, itself, that comes to us was caused to come by the stars and other things out there. To say it isn't is a contradiction to all astronomy.
Combine that with the knowledge we have on earth of all the multitudes of causes, and the fact that we don't have even one example of anything without a cause, and all you have is more cause and still zero spontaneity without cause.
We might have evidence that there are a few hundred other planets out there, but outside of our solar system, we still don't have proof for them. Until we actually get pictures of them, there could be other causes for the effects that lead us to believe there are other planets.
If you want to be that critical, you might as well conclude that nothing exists, and that everything that we think that exists, including our thinking and identity is all spontaneous imagination of nothing. Scientifically speaking there is zero causelessness. In fact, causelessness doesn't even fit within the parameters of anything that makes sense.
Check into it.
It simply doesn't follow like that. It doesn't matter if you know the causes of objects or planets, the universe is as a whole is way different, you can't solve the problem like this, otherwise science would have done it already. We simply don't know if everything has a cause or not, you can keep claiming we do but we don't.
''Scientifically speaking there is zero causelessness'' No.
Sounds like you think that just because you have the ability to think something up, that it must exist somewhere. Well, it does. In virtual form, in your head. It's called art, not science.
Show some proof for causelessness. Nothing in the universe indicates that such is even possible. The fact that we don't know that something is possible or is not possible, isn't scientific proof that it might be. Causelessness falls into the category of scientifically impossible because of the infinite odds against it - countless trillions to zero - and, because it doesn't even make sense.
Scientifically speaking, that is proof... by the odds.
People like you would rather look at the odds against winning a lottery, and suggest that you might win it because somebody has to. The odds against causelessness are way more than those against you winning the lottery. But you like to go on to say that it might be there somewhere. Get a grip.
