Have to work by hand
We humans do still have measuring tools, so I am not sure why this question comes up, but if for some reason we were to lose all of our measuring tools, then we would just have to make estimates. Or create new tools.
Yes, early humans did use wood to make tools. They would shape the wood by carving, cutting, and smoothing it to create functional tools for various purposes such as hunting, cooking, and building. Wood tools were essential for their survival and daily activities.
Early humans made tools by using materials such as stone, bone, and wood. They would shape these materials by striking them against each other to create sharp edges or points. This process of intentionally shaping tools is known as flintknapping and it allowed early humans to hunt, prepare food, and create other items for survival.
Early humans would have first gone to Europe. Australia is a island and early humans would have probably walked to europe far before they rode the ocean to Australia.
It wasn't, really...There were rivers, streams and ponds just like today and most early settlements were puposedly near to natural sources of water. If we are talking about finding underground, hidden sources of water the answer would be that early humans had only very primitive tools to get at those sources.

No life would still go on without humans
Early humans likely learned to make weapons first, as they would have needed tools for hunting and protection. However, evidence suggests that the control and use of fire came shortly after, aiding in cooking food, providing warmth, and offering protection from predators.
Early humans were likely hunter-gatherers who lived in small groups, relied on stone tools for various activities, and had a nomadic lifestyle, moving from one place to another in search of food and resources. They would have also developed basic forms of social organization and communication to survive and thrive in their environments.
Early humans likely sought safety by living in groups, utilizing tools and weapons for defense, and establishing social hierarchies for protection. They likely sought out shelter in caves or constructed rudimentary shelters to protect themselves from predators and the elements. Additionally, their knowledge of the environment and their ability to communicate and cooperate with one another would have also contributed to their safety.
Early pliers were probably invented many times by many different people. Wooden, and then bronze, pliers were in use before 3000 BC. When fire was tamed by early humans, they used a wooden stick to manage the coals. Then two sticks would be used to lift and move hot objects. The men and women would be highly motivated to develop rough tongs and early plier-like tools in order to manage the cooking without getting burned. Early forging of metals saw the widespread use of pliers for handling the hot metal.
because without it animals and humans would die!
