Why is there no 2d, 3d or 4d life on Venus ?

[Bring4th_Austin]

Not sure I completely understand the reason for the question. It seems completely reasonable to me that the planet went through a natural cycle which may have included loosing its water (supported theory) or some other sort of natural cycle which would lead to making it unable to support lower density life.

Of course, 4D might be able to survive on the surface, but considering they must still eat living 2D food stuffs, since 2D food stuffs cannot be cultivated on Venus, it cannot "support" 4D life.

Like stars, I don't view the life cycles of planets as infinite...

first of all, even with our current science, water being a requirement for life to exist is debatable, even if not waning.

but more importantly, Ra says the materials used for life is totally dependent on what materials available in an environment, upon a question don asked about there being some cells on the planet based on a different element.

this means that water is not a requirement for life. life can happen with whatever materials available on a planet.

'life cycle of a planet' is something debatable in itself and part of the question here. the question is what is that life cycle.

With this thinking, you should expand your question. Why doesn't 2D-4D life exist on Mars, since life uses what is available? Just because the biosphere was destroyed to support life like ours, doesn't mean it can't support life in the manner you're talking about. Why not Jupiter? Why not Uranus? Why not Pluto? Why not on the Sun? Why not in the middle of outer space where there is no planet?

You can debate the fact all you want, but it is readily observable in my perception that life requires some sort of environment other than "what materials are available," despite what Ra says. I don't feel like it's too much of a stretch to say that requirement is for the 1D elements to be able to interact with each other.
