Oh come on, universe spanning fungus is in a whole different... ahem... universe from things that can be easily handwaved (all new engines had new nacelle yada yada tech that didn't f up space... or even they just teched a tech and fixed the current engines) or are limited in scope (yes, crazy earth like planets, even thousands or millions of them, are far more likely than anything at all being midichlorians of all time and space). If you can't see the difference in scope of absurdity, I've got a lovely bridge to sell you that's just one bridge but it will lead you to every city on earth.
