The Earth-like structure is more or less a belief. Plus, if no probe has landed on the surface of Venus in three decades, then Venus could've changed massively and we wouldn't know how much of a change it has because we can't land on Venus. It isn't our fault that we can't land though, as Venus' clouds are very thick. The atmosphere itself is very thick on Venus, which makes it harder for exploration to occur. It was said probes can't last for more than a few hours.
