I don&#x27;t know, it may be the current intellectual culture&#x27;s speciesism that we often think that. For instance, they may have many modes of perception better than math. Or even if they have a &quot;math&quot; sense that&#x27;s oddly like ours, they may be unaware of it because it&#x27;s unconscious... in their underlying circuitry... just like we&#x27;re not built to directly introspect many of our own capacities.<p>We may even be in constant contact with &quot;aliens&quot; now, but unable to perceive them meaningfully. Like most lifeforms maybe couldn&#x27;t tell us apart from a rock or rubber.
