I find this to be a lame argument against exo genesis as well as panspermia. I think it's quite plausible Life formed, or began forming, as soon as was possible in the universe, say some 8-9Gyrs ago, and has since been spreading widely.

It's speculative but rationally so. The abiogenic origin theory is sound and well supported by bio-chemistry. Very Well Supported.
The only real issue is: Did life originate here once or many times? Because it's actually pretty easy for life to form...

Curious, the wiki entry for abiogenesis states,
"There is no truly "standard model" of the origin of life. Most currently accepted models draw at least some elements from the framework laid out by the Oparin-Haldane hypothesis. Under that umbrella, however, are a wide array of disparate discoveries and conjectures..."
and
"As of 2008 no one has yet synthesized a protocell using basic components which would have the necessary properties of life."
