Life has been created in the lab from scratch.
I thought trolling was not allowed on here...

Not sure that anyone is trolling here, but Chris' bold assertion does beg for evidence backing it up.

Just as zero is not equal to infinity, everything coming from nothing is illogical.

"From scratch" is ill defined.

Agreed, but I used it first in this thread, so what I meant by "from scratch" is from non living raw materials. Just from elements and chemicals naturally present but not derived from prior life. From just what true abiogenesis would begin with.

Even the respected "Sky at Night" prog on BBC TV last night raised no contradictions. Just, "there's no way that phosphine can form without life!"
What they actually said was "There's no way we know of that this amount of phosphine can form without life". The amount detected is thousands of times more than would be expected by purely chemical reactions. A biochemist interviewed said he'd tried reactions with dozens of combinations of compounds known to exist on Venus; as expected, none of them produced more than traces of phosphine.

And it can't build up over time, like atmospheric oxygen did in the Oxygen Catastrophe on Earth, billions of years ago; something else that was mentioned was that the stuff breaks down fairly quickly under normal Venus atmospheric conditions. Any phosphine detected had to have been produced at most a few hours before.
This universe shipped by weight, not by volume.
Some expansion of the contents may have occurred during shipment.
