Ok, first of all this depends on what you mean by heaven.
True, but I meant something like any assumption about what reality is that is not based on all available data. Generally "heaven" is a religious concept and as such, there are many different heaves contradicting one another. But they're not even theories, they're just ideas.

But isn't assuming there is no heaven a similarly flawed viewpoint?
Not if it is not an assumption but a hypothesis from all available data. It is extremely unlikely that "heaven" exists in any way shape or form close to what most religions surmise. The religions and their ideas are based on lots of contradictions and many things are provably false as more and more research is done. Their ideas of heaven are intimately linked with their ideas about "God(s)", which are of course often in opposition to one another, but also self-contradicting even within each individual source. And the more we observe reality, the less we see that it works the way religions try to tell us it does. Not to mention the source of these religions which to a large degree is known, and how they were passed down, etc.

However that does not necessarily mean that the goal is not attainable by any method. I just wouldn't throw out any possibilities on the nature of reality without sufficient evidence to disprove them.
Who defines what is sufficient though? I think there's plenty of data already to make some ideas highly improbable and others much more likely. Generally any religious ideas about God and/or Heaven go against much of the data that we already have about the universe and how things work, and don't work. And often it even goes against some of the most fundamental assumptions about reality that we have - that are the root assumptions which all logic/math is based on. We know that these assumptions never failed us before, and making logical inferences from available data is the only tool we have to figure anything out or do anything, otherwise math/logic wouldn't even exist or have any application, there wouldn't be an objective reality that we could ever understand or do anything with.
One such example would be the first words in the Bible, "In the beginning..." and right away we have a problem. Beginning of what? What happened before the beginning? And so on. And those are important questions because without answering them in a logical manner that is consistent with our fundamental logical assumptions, that statement would have absolutely no meaning (at least to us humans). Explaining it away by saying "God is above all logic or sense, and he can make contradictions exist cuz he's God. He can create a stone he cannot lift" does not in any way help support that statement or address the problems with it. But I still leave the possibility open that spaghetti monster created all things and we go to the spaghetti kingdom when we die, together with all the other equally improbable heaven ideas. But I still consider them (most of them) extremely improbable.
