It’s in english language.

the setting was in a forest where a couple seem to have woke up from a long sleep. the girl was bitten by a snake on her knee and then the venom or sting was alive and it actually crawled under the skin from knee up to her legs. the guy had to cut open the skin on her leg where the venom/sting  was to release it.

After that scene they saw car remains and they did not know it was call car. they saw photograph and they called it something else other than picture/photograph because they do not know what these were.

the leaders/elders wanted the couple to mate to reproduce but they felt like it was not right.

later they found out that the planet actually had extinct and that they seem to just have been cloned by some futuristic beings and used whatever is left of the human DNA that they found on the planet.

movie was late 90’s i guess, watched it on HBO but hose are the only scenes I could remember.
