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

Fast search and quick example/link

When the data from the Magellan mission did come through though, it surprised many scientists, as there were only a tenth the amount of craters that would be expected had Venus been as old as we thought it was, and the ones which were there were all found to be relatively fresh. There are now two theories for this - one is that volcanic eruptions destroy craters as fast as they are made so there will always be a constant number of craters on Venus, and the other is that 500 million years or so ago, volcanic eruptions resurfaced the planet, destroying all previous craters. Another thing these space probes found was that at least 85% of Venus is covered by volcanic rock! These are mostly from lava flows and form the planet's vast plains.

Notice the pics. Magellan has produced seemingly good pics of the surface.

But main thing is that the surface IS TOO YOUNG....
