Question

tried to meet with the Lord, even they were knowing that Rama is the Lord Vishnu.

Answer 1

Very simple explanation can be given for your question.

All sages knew what was happened earlier, what was going then and what would happen next. Knowing the course of events they stayed together where they were. Infact sages guide Rama for his subsequent destinations in the forest.

This is evident by the following:
Reference 1:
Aranya Kanda: Chapter [Sarga] 5
Rama after killing demon Viradha enters the hermitage of Sage Sharabhanga, as advised by the dying demon Viradha in the previous episode. Sage Sharabhanga refuses the invitation of Indra to come to heaven, but awaits the arrival of Rama to see him with his own eyes. After seeing Rama, Seetha and Lakshmana, and also showing next course of their journey, that Sage enters the yogic fire and ascends to Brahma's abode.

"eSa panthaa naravyaaghra muhuurtam pashya taata maam |
yaavat jahaami gaatraaNi jiirNaam tvacam iva uragaH ||"
3-5-38

esha panthaa nara vyaaghra= this is, the way, manly-tiger; taata= oh, sire; muhuurtam maam pashya= for a moment, me, see; yaavat jiirNaam tvachaam= till, withered, skin, iva uragaH= like, a snake's moult [like snake's cast skin]; gatraani= body parts; jahaami= I forsake.

"This is the only way, oh, manly-tiger, and oh, sire, see me for a moment, till I forsake these body parts of mine, like a snake casting its withered moult" [3-5-38]

Sage Sharabhanga said, eSha panthaa naravyaaghraH meaning that 'this is the only recourse, oh, manly-tiger.' Here Rama asked Sage Sharabhanga to show a place to dwell. Sharabhanga's hermitage itself will now become vacant after the sage's ascension to heavens. But it is not shown to Rama to stay, instead yet another distant place is shown. All these Sages and Saints show only one path that Rama, Seetha and Lakshmana have to travel, i.e., towards Ravana, the evil on earth. From here they are directed to Sage Suteekshna's hermitage, there from to Sage Agastya's hermitage, and there from, to still deeper place in forests, called Panchavati. According to Kaikeyi's banishment Rama need not travel this far, but could have resided in some near-about forests of River Ganga. But one after the other, either demons who became celestials or sages who are going to become divinities, all usher Rama southward, i.e., towards the dominions of demons, whom Rama has to eradicated from earth. 'If Rama were to enter into Panchavati, a powerful dominion of demons like Khara and Dushana, alleging their loyalties to Ravana, it is definite that an encounter will ensue and Rama will start eradicating one after the other, and ultimately ending with Ravana...' this appears to be the logic of all the sages. As such Rama is asked to go on travelling towards the evil side of the earth, for all of the sages know about Rama's destination.

Reference 2:
Aranya Kanda: Chapter [Sarga] 6
After the heavenward journey of Sage Sharabhanga, Rama is approached by others sages and hermits. They inform him about the atrocities of demons around that place. They all ask Rama to eradicate the menace and Rama vows to do so, in order to keep up the tranquillity of those hermitages, and also to obliterate the menace of demons from earth.

Kanda 3- Sarga 6- Verse 9
"vishrutaH triSu lokeSu yashasaa vikrameNa ca |
pitR^i vratatvam satyam ca tvayi dharmaH ca puSkalaH || "

[tvam= you are]; triSu lokeshu yashasaa vikrameNa ca vishrutaH= in three, worlds, by your repute and valour well, renowned; tvayi= in you; pitR^iu vratatvam satyam ca= to father, devotion, truthfulness, also; pushkalaH= abounding; dharmaH ca= righteousness, even [is there].

"You are well renowned in all the three worlds by your repute and valour, and in you abounding are the virtues like truthfulness and devotion to your father, and even righteousness too, is there." [3-6-9]

The above is the apparent meaning. The subtext is "Are you, the supreme charioteer of Ikshvaku dynasty alone, like Indra for celestial beings? And are you the supreme charioteer of this earth and earthlings alone? Not so...you are the Supreme of the whole Universe, therefore your reputation is well known in all the three worlds. Thus you the Omni-Luminescent entered in Ikshvaku dynasty in the form of Rama, to perform your duties like abiding by father's word, with your usual qualities like abounding virtuousness, safeguarding dharma in respect of your own creation/ maintenance..." Thus this is the confrontation-like- addressing of the enlightened sages.

"tvaam aasaadya mahaatmaanam dharmaj~nam dharma vatsalam |
arthitvaat naatha vakSyaamaH tat ca naH kSantum arhasi ||" 3-6-10

mahaatmaanam= great soul; dharmaj~nam= knower of righteousness; dharma vatsalam= virtue, patron of; tvaam arthitvaat aasaadya= you, like begging, on getting at [we beg to state as we have come across you]; vakshyaamaH= we can tell you [petition to you]; naatha= oh, protector; naH= our; that= that [special or personal] begging; kshantum arhasi= to pardon, will be apt of you.

"You are the great-souled one, knower of righteousness and a patron of virtue... such as you are, on approaching you we beg to state something for which we may please be excused" [3-6-10]

Special application to god is a waste. His mercy has to flow on its own accord. Why beg him to perform his own duty? If by mistake, an appeal is made to god to alleviate a personal problem, his pardon may to be begged, but he is not be begged to do favours. Here the sages on one hand say that 'you have come here in the incarnation of Rama to eradicate evil...' At the same time, they say 'we have an appeal for the same...' This begging off, is as per social custom, made to the apparent ruler of the kingdom, not to the innate Divine.

Answer 2

One can never be sure. They knew the lord was to come, but still they cannot be sure. Sometimes mistakes happen, and everyone waits for the lord to show himself, supernaturally maybe with miracles, still we can't be sure. To doubt is human and sometimes it is better to be skeptical, then to make a mistake.
