No not anything conceivable only things that have a chance to exist.
Good point, I agree that is more precise and correct. However we don't know which things that are conceivable don't have a chance to exist, and in the context of this discussion, we actually need to know that something has an exactly 0% chance to exist, otherwise given an eternity it will.

For example, a giant solid gold planet can physically exist in this universe but there is no probable process for it to arise. I suppose a super developed alian race could search the galaxy for all it's hold and create one.. But for what purpose?
This is an example of something that can exist but will never exist.
I'm not sure that I agree on this. The process by which a gold planet arises needs to not just be at the level of 'not probable', it has to be impossible, correct? Otherwise I'm not sure why, "In an infinity of existence anything that has a probability of happening will and already did.", wouldn't apply. (And thinking about it further, I don't know that I necessarily am sure that anything that can happen will happen given an infinity, it sounds logical, but infinity is tricky and I'm not a math/philosophy pro. An infinite set of numbers does not have to contain all possible numbers; it may just come down to how we're definining 'probability' in this sense.)

Other things however like intelligence, sentience, can and do exist. The benefit of sentience is that it's remarkably good at reproducing itself therefore selection will favor it. Intelligent sentience should at some point pervade the universe. Looking backwards, it's likely that it already has.
We can us AI as an example. If we ever manage to create AI worlds and universes, we then proove that it can be done. If we make multiples of them ( and we would) then we have a statistic. Let's say that 1% of all intelligent races create 100 ai universes.
Do you see what happens now? 99% of all sentient life and their environments should be a creation of another. There is no reason to assume our universe is the top of the food chain. In all likely hood we are within the 99%. All we have to do is accomplish created AI worlds ( and we are very close), then the odds of us being created jump way up. If you look at quantum mechanics some of the fundamental laws of nature behave very digital like.
Hmm, I guess 'AI' means something a little different to me, I'm not sure that AI as it's usually defined is typically referred to as 'sentient', if I'm following you correctly. Are you saying that the term 'AI' as you are using it covers humans also? If so, I don't think 'we are very close' to creating AI worlds populated with creatures that have sentience in the same way we do, but I may just be unclear on what you mean. Although what it would take to make a 'sentient' AI and how we'd know is a very interesting question, no doubt.

In an infinit of existence anything that has a probability of happening will and already did. This would mean highly evolved sentience as well. Its really the only answer to the anthropic principal.
But I think the question then gets moved to, 'what things are actually possible and how do we know they are?', under this framework, and we are kinda presuming that 'highly evolved sentience', to the god/aggregate consciousness level, is possible. Spider webs exist, and I can envision a scenario that due to selective pressures over an infinity of existence that spider webs may evolve to be unbreakable, it might be possible. But how do I know? It doesn't seem that just because intelligence (spider webs) exists doesn't really give us all the information we need to then say that god (unbreakable webs) will likely exist given an infinity. As far as the anthropic principle it's always seemed to me somewhat obvious and banal, although there is a lot of interesting discussion surrounding it. Thought provoking stuff regardless!
