2 before主句的时态可以是现在完成时吗

老师好!向老师请教一个句子:

Though they’ve been around long before we walked on the earth, sharks still attract us to this day.

请问:they’ve been around long before we walked on the earth 中的 have been around 的时态是否合理,是否应改为had been around

作者偷了一个懒,句子省略了一个since介词短语:

Though they’ve been around since a time long before we walked on the earth, sharks still attract us to this day.

long before we walked on the earth是修饰time的定语,现在完成时表示自从人类出现以前很久一直到现在,鲨鱼都是存在的。
