Well, we can assume things but so far, as far as I know, all the theories proposing an universal "proto-human" language have been widely rejected by scientists. We have the hipothetic roots from Proto-Indo-European but I don't know much about the etymology of the Hebrew numerals. Maybe they were borrowed/affected by an IE language. Someone should look for their etymology in Hebrew. But I don't think it's likely that they're somehow connected.
Well, the online etymological dictionary claims that "seven" comes (ultimately) from the Proto-Indo-European "septm," along the same linguistic branch as other Germanic languages. And "septm" is also claimed as the root of the Latin "septem" (makes sense) which would make it the root for all of the Romance languages as well. Considering the time period that Hebrew is believed to have developed as a distinct language, cross-contamination probably would've gone the other way. Don't know if that's likely, either, since שבע is supposed to be connected to the word for resting. But the PIE "septm" is argued to have always been related to the number.
So after that quick bit of digging, I'm now more inclined to believe it's a very strange coincidence.
Well, if you watch Kimi no Na wa[君の名は]ーa great film I'd sayーyou would realize that 名[na] is the word that means "name", while 前[mae] means "in front". It's a super coincidence, which makes us wonder how many other unrelated words with meanings out there; i.e. false cognates. I mean, even 坊や[bo•ya], which means "boy" sounds too close for comfort to not be related to the English word.
Well, as Hebrew has שֵׁשׁ and שֶׁ֫בַע, Aramaic שִׁית and שְׁבַע and Arabic سِتَّة and سَبْعَة, its original form must be something like ʃidθ- and ʃabʿ, while Proto-European is postulated to have swéḱs and septḿ̥. I personally do not find them incredible similar, but judge yourself.
Well, in the creationism, there are very well sustained theories, of course we can't forget the Babylon Tower event. It has an effect of waves (like a stone on a lake) on the cultures when expanding through the world.. the farthest ones, the lesser developed. (But no his languages)
