Agreed totally.....any race that exists alongside our timeline could have attained intergalactic and dimensional travel along a totally symbiotic science that we just do not have, like many have said, their ships look ''grown'' and not ''built'', I remember and excellent series on TV ages ago called ''Lex'' and the ship was ''born'' and only one man could pilot it, the pilot that was ''joined'' to it....''Lex'', I cannot remember the ships name though.I don't necessarily agree with 1000's of years ahead. However it would look alien because Lore (used to) depict the Thargoids had Biotech ships. Hence the reason the Mycoid virus did their ships as well as the creatures themselves.
