How to create a service instance from a static function ?

There is no way to get a ServiceFactory from $GLOBALS['app'] ?

Not possible. There is no any global variable in espocrm.

I want to do this in a static function. Is there any way to get a reference from the global $app variable for example ?

  $activityService = $this->getServiceFactory()->create('Activities');
