Bhala isigaba esiphikisa isimangalo somuntu osebenza naye sokuthi izakhiwo zasendulo ezinjengeStonehenge, iGreat Pyramid ziwubufakazi bemisebenzi ye-UFO eMhlabeni
Kunezimpikiswano eziningana ezinamandla ngokumelene nokuphetha ngokuthi izinhlanga zabangaphandle zakha izakhiwo ezinjengeStonehenge noma amaPhiramidi. Okokuqala, kunobufakazi bokuthi lezi zakhiwo ezinhle kakhulu zakhiwa abantu. Ngokwesibonelo, amathuna abakhi bamaphiramidi atholakala eduze kwePhiramidi Elikhulu (kunensalela yabantu!). Ubuchwepheshe bokuthutha nokuhlanganisa amatshe amakhulu eStonehenge buye babonakala ukuthi babutholakala kubantu ngaleso sikhathi. Okwesibili, ngenxa yokuthi umkhathi mkhulu kangaka, amathuba okuthola iplanethi eyodwa encane phakathi kwezigidigidi ayoba mancane kakhulu. Uma ubuhlakani bamazwe angaphandle ngempela babutholile iplanethi yethu eyodwa ehlala abantu, akunakwenzeka ukuthi babumane nje bakha izakhiwo ezimbalwa futhi bagwema noma ikuphi ukuxhumana okwengeziwe noMhlaba nabakhileyo kuwo. Ezesayensi, i-Occam's Razor (incazelo elula kunazo zonke iyona engcono kunazo zonke) iyisimiso esiqondisayo futhi kuze kube yilapho kunobufakazi obuningi bokuvakashelwa abokufika kungeke kube ukuhlakanipha ukugxumela esiphethweni sokuthi abokufika bakha lezi zakhiwo.
